Re: flink k-means on hadoop cluster

i start the yarn-session.sh with sudo
and than the flink run command with sudo,
i get the following exception:

2015-06-04 17:15 GMT+02:00 Robert Metzger <[hidden email]>:
As the output of the "hadoop" tool indicates, it expects two arguments, you only passed one (777).
The second argument it is expecting is the path to the file you want to change.

In your case, it is:
hadoop fs -chmod 777 /user/cloudera/outputs


The reason why 
hadoop fs -chmod 777 *
does not work is the following: the * is evaluated by your local bash and expanded to the files which are present in your current, local directory. The bash expansion is not able to expand to the files in HDFS.

you understand?

2015-06-04 17:04 GMT+02:00 Robert Metzger <[hidden email]>:
It looks like the user "yarn" which is running Flink doesn't have permission to access the files.

Can you do "sudo su yarn" to become the "yarn" user. Then, you can do "hadoop fs -chmod 777" to make the files accessible for everyone.

how i must set the files in the hdfs?
quickstart.cloudera:50075/home/cloudera/output?

2015-06-04 16:51 GMT+02:00 Robert Metzger <[hidden email]>:
Once you've started the YARN session, you can submit a Flink job with "./bin/flink run <pathToYourJar>".

The jar file of your job doesn't need to be in HDFS. It has to be in the local file system and flink will send it to all machines.

2015-06-04 16:31 GMT+02:00 Robert Metzger <[hidden email]>:
Yes, you have to run these commands in the command line of the Cloudera VM.

you mean run this command on terminal/shell and not define a hue job?

2015-06-04 16:25 GMT+02:00 Robert Metzger <[hidden email]>:
It should be certainly possible to run Flink on a cloudera live VM

I think these are the commands you need to execute:

wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz
cd flink-0.9-SNAPSHOT/
export HADOOP_CONF_DIR=/usr/lib/hadoop/etc/hadoop/
./bin/yarn-session.sh -n 1 -jm 1024 -tm 1024

If that is not working for you, please post the exact error message you are getting and I can help you to get it to run.

hi robert,

i think the problem is the hue api,
i had the same problem with spark submit script,
but on the new hue release, they have a spark submit api.

i asked the group for the same problem with spark, no reply.

i want test my app on local cluster, before i run it on the big cluster,
for that i use cloudera live. maybe it give an other way to test flink on a local cluster vm?

2015-06-04 16:12 GMT+02:00 Robert Metzger <[hidden email]>:
Hi Paul,

why did running Flink from the regular scripts not work for you?

I'm not an expert on Hue, I would recommend asking in the Hue user forum / mailing list: https://groups.google.com/a/cloudera.org/forum/#!forum/hue-user.

2015-06-02 14:50 GMT+02:00 Robert Metzger <[hidden email]>:
I would recommend using HDFS.
For that, you need to specify the paths like this: hdfs:///path/to/data.

nice,

which file system i must use for the cluster? java.io or hadoop.fs or flink?

2015-06-02 14:29 GMT+02:00 Robert Metzger <[hidden email]>:
Hi,
you can start Flink on YARN on the Cloudera distribution.


These are the commands you need to execute
wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz

sorry, i see my yarn end before i can run my app, i must set the write access for yarn, maybe this solve my problem.

2015-06-04 17:15 GMT+02:00 Robert Metzger <[hidden email]>:
As the output of the "hadoop" tool indicates, it expects two arguments, you only passed one (777).
The second argument it is expecting is the path to the file you want to change.

In your case, it is:
hadoop fs -chmod 777 /user/cloudera/outputs


The reason why 
hadoop fs -chmod 777 *
does not work is the following: the * is evaluated by your local bash and expanded to the files which are present in your current, local directory. The bash expansion is not able to expand to the files in HDFS.

you understand?

2015-06-04 17:04 GMT+02:00 Robert Metzger <[hidden email]>:
It looks like the user "yarn" which is running Flink doesn't have permission to access the files.

Can you do "sudo su yarn" to become the "yarn" user. Then, you can do "hadoop fs -chmod 777" to make the files accessible for everyone.

how i must set the files in the hdfs?

2015-06-04 16:51 GMT+02:00 Robert Metzger <[hidden email]>:
Once you've started the YARN session, you can submit a Flink job with "./bin/flink run <pathToYourJar>".

The jar file of your job doesn't need to be in HDFS. It has to be in the local file system and flink will send it to all machines.

Yes, you have to run these commands in the command line of the Cloudera VM.

2015-06-04 16:25 GMT+02:00 Robert Metzger <[hidden email]>:
It should be certainly possible to run Flink on a cloudera live VM

I think these are the commands you need to execute:

wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz
cd flink-0.9-SNAPSHOT/
export HADOOP_CONF_DIR=/usr/lib/hadoop/etc/hadoop/
./bin/yarn-session.sh -n 1 -jm 1024 -tm 1024

If that is not working for you, please post the exact error message you are getting and I can help you to get it to run.

hi robert,

i think the problem is the hue api,
i had the same problem with spark submit script,
but on the new hue release, they have a spark submit api.

i asked the group for the same problem with spark, no reply.

i want test my app on local cluster, before i run it on the big cluster,
for that i use cloudera live. maybe it give an other way to test flink on a local cluster vm?

2015-06-04 16:12 GMT+02:00 Robert Metzger <[hidden email]>:
Hi Paul,

why did running Flink from the regular scripts not work for you?

I'm not an expert on Hue, I would recommend asking in the Hue user forum / mailing list: https://groups.google.com/a/cloudera.org/forum/#!forum/hue-user.

I would recommend using HDFS.
For that, you need to specify the paths like this: hdfs:///path/to/data.

Hi,
you can start Flink on YARN on the Cloudera distribution.


These are the commands you need to execute

Re: flink k-means on hadoop cluster

i have change the permissions from the cloudera user and try the following command.
and the files exist on hdfs ;) i set the files in my properties file like "flink.output=/user/cloudera/outputs/output_flink"
i get the same exception again, maybe the problem have an other reason?

2015-06-04 17:15 GMT+02:00 Robert Metzger <[hidden email]>:
As the output of the "hadoop" tool indicates, it expects two arguments, you only passed one (777).
The second argument it is expecting is the path to the file you want to change.

In your case, it is:
hadoop fs -chmod 777 /user/cloudera/outputs


The reason why 
hadoop fs -chmod 777 *
does not work is the following: the * is evaluated by your local bash and expanded to the files which are present in your current, local directory. The bash expansion is not able to expand to the files in HDFS.

you understand?

2015-06-04 17:04 GMT+02:00 Robert Metzger <[hidden email]>:
It looks like the user "yarn" which is running Flink doesn't have permission to access the files.

Can you do "sudo su yarn" to become the "yarn" user. Then, you can do "hadoop fs -chmod 777" to make the files accessible for everyone.

how i must set the files in the hdfs?
quickstart.cloudera:50075/home/cloudera/output?

2015-06-04 16:51 GMT+02:00 Robert Metzger <[hidden email]>:
Once you've started the YARN session, you can submit a Flink job with "./bin/flink run <pathToYourJar>".

The jar file of your job doesn't need to be in HDFS. It has to be in the local file system and flink will send it to all machines.

okay, now it run on my hadoop.
how i can start my flink job? and where must the jar file save, at hdfs or as local file?

2015-06-04 16:31 GMT+02:00 Robert Metzger <[hidden email]>:
Yes, you have to run these commands in the command line of the Cloudera VM.

you mean run this command on terminal/shell and not define a hue job?

2015-06-04 16:25 GMT+02:00 Robert Metzger <[hidden email]>:
It should be certainly possible to run Flink on a cloudera live VM

I think these are the commands you need to execute:

wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz
cd flink-0.9-SNAPSHOT/
export HADOOP_CONF_DIR=/usr/lib/hadoop/etc/hadoop/
./bin/yarn-session.sh -n 1 -jm 1024 -tm 1024

If that is not working for you, please post the exact error message you are getting and I can help you to get it to run.

hi robert,

i think the problem is the hue api,
i had the same problem with spark submit script,
but on the new hue release, they have a spark submit api.

i asked the group for the same problem with spark, no reply.

i want test my app on local cluster, before i run it on the big cluster,
for that i use cloudera live. maybe it give an other way to test flink on a local cluster vm?

2015-06-04 16:12 GMT+02:00 Robert Metzger <[hidden email]>:
Hi Paul,

why did running Flink from the regular scripts not work for you?

I'm not an expert on Hue, I would recommend asking in the Hue user forum / mailing list: https://groups.google.com/a/cloudera.org/forum/#!forum/hue-user.

i try to run the flink script in the hdfs, it's not work.

best regards,

2015-06-02 14:50 GMT+02:00 Robert Metzger <[hidden email]>:
I would recommend using HDFS.
For that, you need to specify the paths like this: hdfs:///path/to/data.

nice,

which file system i must use for the cluster? java.io or hadoop.fs or flink?

2015-06-02 14:29 GMT+02:00 Robert Metzger <[hidden email]>:
Hi,
you can start Flink on YARN on the Cloudera distribution.


These are the commands you need to execute
wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz

Re: flink k-means on hadoop cluster

Pa Rö
here my main class:
	public static void main(String[] args) {		
		//load properties
		Properties pro = new Properties();
		try {
			pro.load(FlinkMain.class.getResourceAsStream("/config.properties"));
		} catch (Exception e) {
			e.printStackTrace();
		}
		int maxIteration = Integer.parseInt(pro.getProperty("maxiterations"));
		String outputPath = pro.getProperty("flink.output");
		// set up execution environment
		ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
		// get input points 
		DataSet<GeoTimeDataTupel> points = getPointDataSet(env);
		DataSet<GeoTimeDataCenter> centroids = null;
		try {
			centroids = getCentroidDataSet(env);
		} catch (Exception e1) {
			e1.printStackTrace();
		}
		// set number of bulk iterations for KMeans algorithm
		IterativeDataSet<GeoTimeDataCenter> loop = centroids.iterate(maxIteration);
		DataSet<GeoTimeDataCenter> newCentroids = points
			// compute closest centroid for each point
			.map(new SelectNearestCenter()).withBroadcastSet(loop, "centroids")
			// count and sum point coordinates for each centroid
			.groupBy(0).reduceGroup(new CentroidAccumulator())
			// compute new centroids from point counts and coordinate sums
			.map(new CentroidAverager());
		// feed new centroids back into next iteration
		DataSet<GeoTimeDataCenter> finalCentroids = loop.closeWith(newCentroids);
		DataSet<Tuple2<Integer, GeoTimeDataTupel>> clusteredPoints = points
			// assign points to final clusters
			.map(new SelectNearestCenter()).withBroadcastSet(finalCentroids, "centroids");
		// emit result
		clusteredPoints.writeAsCsv(outputPath+"/points", "\n", " ");
		finalCentroids.writeAsText(outputPath+"/centers");//print();
		// execute program
		try {
			env.execute("KMeans Flink");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
maybe i can't use the following for the hdfs? 
clusteredPoints.writeAsCsv(outputPath+"/points", "\n", " ");
finalCentroids.writeAsText(outputPath+"/centers");//print();

i have change the permissions from the cloudera user and try the following command.
and the files exist on hdfs ;) i set the files in my properties file like "flink.output=/user/cloudera/outputs/output_flink"
i get the same exception again, maybe the problem have an other reason?

The second argument it is expecting is the path to the file you want to change.

In your case, it is:
hadoop fs -chmod 777 /user/cloudera/outputs


The reason why 
hadoop fs -chmod 777 *
does not work is the following: the * is evaluated by your local bash and expanded to the files which are present in your current, local directory. The bash expansion is not able to expand to the files in HDFS.

you understand?

2015-06-04 17:04 GMT+02:00 Robert Metzger <[hidden email]>:
It looks like the user "yarn" which is running Flink doesn't have permission to access the files.

Can you do "sudo su yarn" to become the "yarn" user. Then, you can do "hadoop fs -chmod 777" to make the files accessible for everyone.

how i must set the files in the hdfs?

2015-06-04 16:51 GMT+02:00 Robert Metzger <[hidden email]>:
Once you've started the YARN session, you can submit a Flink job with "./bin/flink run <pathToYourJar>".

The jar file of your job doesn't need to be in HDFS. It has to be in the local file system and flink will send it to all machines.

2015-06-04 16:31 GMT+02:00 Robert Metzger <[hidden email]>:
Yes, you have to run these commands in the command line of the Cloudera VM.

2015-06-04 16:25 GMT+02:00 Robert Metzger <[hidden email]>:
It should be certainly possible to run Flink on a cloudera live VM

I think these are the commands you need to execute:

wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz
cd flink-0.9-SNAPSHOT/
export HADOOP_CONF_DIR=/usr/lib/hadoop/etc/hadoop/
./bin/yarn-session.sh -n 1 -jm 1024 -tm 1024

If that is not working for you, please post the exact error message you are getting and I can help you to get it to run.

hi robert,

i think the problem is the hue api,
i had the same problem with spark submit script,
but on the new hue release, they have a spark submit api.

i asked the group for the same problem with spark, no reply.

i want test my app on local cluster, before i run it on the big cluster,
for that i use cloudera live. maybe it give an other way to test flink on a local cluster vm?

2015-06-04 16:12 GMT+02:00 Robert Metzger <[hidden email]>:
Hi Paul,

why did running Flink from the regular scripts not work for you?

I'm not an expert on Hue, I would recommend asking in the Hue user forum / mailing list: https://groups.google.com/a/cloudera.org/forum/#!forum/hue-user.

I would recommend using HDFS.
For that, you need to specify the paths like this: hdfs:///path/to/data.

Hi,
you can start Flink on YARN on the Cloudera distribution.


These are the commands you need to execute
wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz

Re: flink k-means on hadoop cluster

rmetzger0
No, the permissions are still not correct, otherwise, Flink would not complan.

The error message of Flink is actually pretty precise: "Caused by: java.io.FileNotFoundException: File /user/cloudera/inputs does not exist or the user running Flink ('yarn') has insufficient permissions to access it."

Does the file exist and does the user "yarn" has permission to access it?

maybe i can't use the following for the hdfs?

2015-06-04 17:15 GMT+02:00 Robert Metzger <[hidden email]>:
As the output of the "hadoop" tool indicates, it expects two arguments, you only passed one (777).
The second argument it is expecting is the path to the file you want to change.

In your case, it is:
hadoop fs -chmod 777 /user/cloudera/outputs


The reason why 
hadoop fs -chmod 777 *
does not work is the following: the * is evaluated by your local bash and expanded to the files which are present in your current, local directory. The bash expansion is not able to expand to the files in HDFS.

you understand?

2015-06-04 17:04 GMT+02:00 Robert Metzger <[hidden email]>:
It looks like the user "yarn" which is running Flink doesn't have permission to access the files.

Can you do "sudo su yarn" to become the "yarn" user. Then, you can do "hadoop fs -chmod 777" to make the files accessible for everyone.

how i must set the files in the hdfs?

2015-06-04 16:51 GMT+02:00 Robert Metzger <[hidden email]>:
Once you've started the YARN session, you can submit a Flink job with "./bin/flink run <pathToYourJar>".

The jar file of your job doesn't need to be in HDFS. It has to be in the local file system and flink will send it to all machines.

Yes, you have to run these commands in the command line of the Cloudera VM.

It should be certainly possible to run Flink on a cloudera live VM

I think these are the commands you need to execute:

wget http://stratosphere-bin.s3-website-us-east-1.amazonaws.com/flink-0.9-SNAPSHOT-bin-hadoop2.tgz
tar xvzf flink-0.9-SNAPSHOT-bin-hadoop2.tgz
cd flink-0.9-SNAPSHOT/
export HADOOP_CONF_DIR=/usr/lib/hadoop/etc/hadoop/
./bin/yarn-session.sh -n 1 -jm 1024 -tm 1024

If that is not working for you, please post the exact error message you are getting and I can help you to get it to run.

i had the same problem with spark submit script,

i asked the group for the same problem with spark, no reply.

i want test my app on local cluster, before i run it on the big cluster,
for that i use cloudera live. maybe it give an other way to test flink on a local cluster vm?

Hi Paul,

why did running Flink from the regular scripts not work for you?

I'm not an expert on Hue, I would recommend asking in the Hue user forum / mailing list: https://groups.google.com/a/cloudera.org/forum/#!forum/hue-user.

I would recommend using HDFS.
For that, you need to specify the paths like this: hdfs:///path/to/data.

Hi,
you can start Flink on YARN on the Cloudera distribution.


These are the commands you need to execute

Re: flink k-means on hadoop cluster

Till Rohrmann-2

I assume that the path inputs and outputs is not correct since you get the error message chown `output’: No such file or directory. Try to provide the full path to the chown command such as hdfs://ServerURI/path/to/your/directory.

I assume that the path inputs and outputs is not correct since you get the error message chown `output’: No such file or directory. Try to provide the full path to the chown command such as hdfs://ServerURI/path/to/your/directory.

Hi Robert,

i have see that you write me on stackoverflow, thanks. now the path is right and i get the old exception:
org.apache.flink.runtime.JobException: Creating the input splits caused an error: File file:/127.0.0.1:8020/home/user/cloudera/outputs/seed-1 does not exist or the user running Flink ('yarn') has insufficient permissions to access it.

i have look at the hdfs and want give the user yarn all permissions:
[cloudera@quickstart bin]$ hdfs dfs -ls

Re: flink k-means on hadoop cluster

hdfs://ServerURI:8020/user/cloudera/inputs should do the trick
