WordCount w/ YARN and EMR local filesystem and/or HDFS
Locked
WordCount w/ YARN and EMR local filesystem and/or HDFS
 
|
I'm trying to use the wordcount example with the local file system, but it's giving me permissions error or it's not finding it. It works just fine for input and output on S3. What
is the correct URI usage for the local file system and HDFS? I have installed Flink on EMR and am just using the flink run script to start the job: % flink run -m yarn-cluster -yn 2 /usr/lib/flink/examples/streaming/WordCount.jar --input

Hi! The input data must be in a filesystem that all cluster nodes can access, like s3, hdfs, a mounted nfs, ... Stephan On Tue, Aug 23, 2016 at 7:54 PM, Foster, Craig <[hidden email]> wrote:

Ah cool, that makes sense then. So you must always stage your files in a HDFS, S3, etc. I can live with that ;) Then here is my HDFS exception...maybe I've got to configure something differently? I think I am using a proper HDFS URI.
For HDFS, I tried this but got a protobuf exception: % hadoop fs -ls /user/hadoop/ Found 2 items drwxrwxrwx - hadoop hadoop 0 2016-08-23 17:49 /user/hadoop/.flink -rw-r--r-- 1 hadoop hadoop 15419 2016-08-23 14:56 /user/hadoop/LICENSE.txt

Shutting down YARN cluster From:
Stephan Ewen <[hidden email]> Hi! The file "/home/hadoop/LICENSE.txt" probably exists only on the machine that starts the job (your workstation, laptop), not in the cluster. The Flink processes in the cluster cannot find the file under that address.
The input data must be in a filesystem that all cluster nodes can access, like s3, hdfs, a mounted nfs, ... Stephan On Tue, Aug 23, 2016 at 7:54 PM, Foster, Craig <[hidden email]> wrote:

I would have to pull in Robert into the loop, but my first guess is that this is a Hadoop version mismatch.
Can you double check that the Hadoop Version for which you download Flink is the same as the one on the cluster? Greetings, Stephan On Tue, Aug 23, 2016 at 8:44 PM, Foster, Craig <[hidden email]> wrote:

I am 99% they are the same since this exists in the EMR yum repo on the cluster.

Hi, the problem is that you are using the wrong Namenode port. The port is 8020, not 50070. On EMR, you actually don't need to specify the Namenode port at all. This command works for me: [hadoop@ip-172-31-23-104 ~]$ flink run -m yarn-cluster -yn 2 /usr/lib/flink/examples/streaming/WordCount.jar --input hdfs:///user/hadoop/test10Mb.db --output hdfs:///user/hadoop/out I hope that does the trick. Let me know if you need further help. Regards, Robert On Tue, Aug 23, 2016 at 8:57 PM, Foster, Craig <[hidden email]> wrote:

Oops! That makes sense not to use the web UI port.
Thanks! Craig From:
