Som, Let us know when you have any problems

Thanks for the info and links.

I had a lot of problems I am not sure what I was doing wrong.

May be conflicts with setup from apache spark.  I think I may need to setup users for each development.

Anyway I kept doing fresh installs about four altogether I think. 

Everything works fine now

Including remote access  of zeppelin on machines across the local area network.

Next step  setup remote clusters

 Wish me luck !

Hi Som, 

You can take a look at flink on zeppelin, in zeppelin you can connect to a remote flink cluster via a few configuration, and you don't need to worry about the jars. Flink interpreter will ship necessary jars for you. Here's a list of tutorials.

1) Get started https://link.medium.com/oppqD6dIg5 2) Batch https://link.medium.com/3qumbwRIg5 3) Streaming https://link.medium.com/RBHa2lTIg5 4) Advanced usage https://link.medium.com/CAekyoXIg5

Hi Tison,

I think I may have found what I want in example 22.

https://www.programcreek.com/java-api-examples/?api=org.apache.flink.configuration.Configuration

I need to create Configuration object first as shown .

Also I think  flink-conf.yaml file may contain configuration for client rather than  server. So before starting is irrelevant. 

I am going to play around and see but if the Configuration class allows me to set configuration programmatically and overrides the yaml file then that would be great.

Thanks.

flink-conf.yaml does allow me to do what I need to do without making any changes to client source code.

But

RemoteStreamEnvironment constructor  expects a jar file as the third parameter also.

RemoteStreamEnvironment(String host, int port, String... jarFiles)

Creates a new RemoteStreamEnvironment that points to the master (JobManager) described by the given host name and port.

You can change flink-conf.yaml "jobmanager.address" or "jobmanager.port" options before run the program or take a look at RemoteStreamEnvironment which enables configuring host and port.

Best,

tison.

Hi,

After running 

$ ./bin/start-cluster.sh

The following line of code defaults jobmanager  to localhost:6123 

final  ExecutionEnvironment env = Environment.getExecutionEnvironment();

which is same on spark.

val spark = SparkSession.builder.master(local[*]).appname("anapp").getOrCreate

However if I wish to run the servers on a different physical computer.

Then in Spark I can do it this way using the spark URI in my IDE.

Conf =  SparkConf().setMaster("spark://<hostip>:<port>").setAppName("anapp")

Can you please tell me the equivalent change to make so I can run my servers and my IDE from different physical computers.
