Hello,
I periodically see in JM log (Flink 12.2):
{"ts":"2021-05-15T21:10:36.325Z","message":"The heartbeat of JobManager with id
be8225ebae1d6422b7f268c801044b05 timed
out.","logger_name":"org.apache.flink.runtime.resourcemanager.StandaloneResourceManager","thread_name":"flink-akka.actor.default-dispatcher-5","level":"INFO","level_value":20000}
How to diagnose/troubleshoot this problem? Why could JobManager, which is
co-located with resource manager timeout, I assume this is unlikely network
issue?
Thanks,
Alexey
