I did try it but this option seems to be for a third party jar. In my case I would need to specify/ship a jar that contains the code where job is being constracted. I'm not clear of

1. how to point to the containg jar 

2. how to test such a submission from my project running in Eclipse

Hi Alexander, 

The signature of the createRemoteEnvironment is 

public static StreamExecutionEnvironment createRemoteEnvironment(
      String host, int port, String... jarFiles);

Which could also ship the jars to execute to remote cluster. Could you have a try to also pass the jar files to the remote environment ?

Best,

Theme:How to deploy dynamically generated flink jobs?

Hi,

I am trying to build a functionality to dynamically configure a flink job (Java) in my code based on some additional metadata and submit it to a flink running in a session cluster.

Flink version is 1.11.2

The problem I have is how to provide a packed job to the cluster. When I am trying the following code

StreamExecutionEnvironment env = StreamExecutionEnvironment.createRemoteEnvironment(hostName, hostPort);
... configuring job workflow here...
env.execute(jobName);

I am getting ClassNotFoundException stating that code for my mapping functions did not make it to the cluster. Which makes sense.

What would be the right way to deploy dynamically configured flink jobs which are not packaged as a jar file but rather generated ad-hoc?

Thanks
