Hi,
As you mentioned, my program contains a loop with infinite iterations. I
was not able to stop by kill -9 command. Instead I killed the entire flink
cluster job. I set up the cluster again with one master and three slaves.
Now when I try to run the code, it is showing the following exceptions.
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The program
execution failed: Communication with JobManager failed: Lost connection to
the JobManager.
