Running Flink jobs directly from Eclipse

[Serhiy Boychenko]

Cheerz,

 

I have been working last few month on the comparison of different data processing engines and recently came across Apache Flink. After reading different academic papers on comparison of Flink with other data processing I would definitely give it a shot. The only issue I am currently having is that I am unable to submit Flink jobs directly from Eclipse (to YARN cluster). I am wondering if you got any guildelines how I could do the submission not from the client but from Eclipse directly? (I was unable to find anything related, with the exception of setting up Eclipse for working on Flink core)

 

Best regards,

Serhiy.

From my side I was starting the YARN session from the cluster:

flink-0.10.1/bin/yarn-session.sh -n 64 -s 4 -jm 4096 -tm 4096

Then getting the IP/port from the WebUI and then from Eclipse:

ExecutionEnvironment env = ExecutionEnvironment.createRemoteEnvironment("xx.xx.xx.xx", 40631, "target/FlinkTest-0.0.1-SNAPSHOT-jar-with-dependencies.jar");

The JAR need to be compiled before.

Hope it helps!

Thanks for the info! It is a bit difficult to tell based on the documentation whether or not you need to put your jar onto the Flink master node and run the flink command from there in order to get a job running. The documentation on https://ci.apache.org/projects/flink/flink-docs-release-1.0/setup/yarn_setup.html isn't very explicit about where you can run the flink command from, and doesn't mention that you can run the job programmatically instead of using the CLI.

For me it was taking the local jar and uploading it into the cluster.

What about YARN(and HDFS) configuration? I put yarn-site.xml directly into classpath? Or I can set the variables in the execution environment? I will give it a try tomorrow morning, will report back and if successful blog about it ofc J

I exported it in an environment variable before starting Flink:

flink-0.10.1/bin/yarn-session.sh -n 64 -s 4 -jm 4096 -tm 4096
