Hello users, I was running an experiment on a very simple cluster with two nodes (one jobmanager and another taskmanager). However after starting the execution, in a few seconds the program is aborted with the error.
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The program
execution failed: Job execution failed.

Can anyone having similar problem solved this issue. I am attaching the
logs also. One of the logs say that the taskmanager ip is unreachable (but
I have successfully pinged and ssh-ed from the job manager to the
taskmanager).
Thanks in advance,
P.S: PFA the logs.
Regards,
Debaditya
