Hello,
I'm trying to run python jobs with the latest master on a cluster and
get the following exception:
Error: The program execution failed: JobManager not reachable anymore.
Terminate waiting for job answer.
org.apache.flink.client.program.ProgramInvocationException: The program
execution failed: JobManager not reachable anymore. Terminate waiting
for job answer.
