Till Rohrmann commented on FLINK-21685:
---------------------------------------
Could you share a bit more details about the job and the exact setup you are
running [~petrizhang]?
In the attached logs, I could see three JobManager instances. One instance only
living from 12:05: to 13:01. It received a SIGTERM at 12:31 but only shut down
13:01. This is strange.
At 12:42 a second instance is started which becomes the leader. A bit later at
(12:54) we see the following snippet in the logs:
{code}
1615207818477197056,Will wait for AWS credentials for up to 60 s.
1615207818921065984,Successfully obtained AWS credentials. Caller:
arn:aws:sts::637664033771:assumed-role/stellar-flink-staging-iam-role/bf1a2c86-stellar-flink-staging-iam-role
1615207817604473088,"Shutting down, got signal: Terminated"
{code}
>From this point onwards the second JobManager seems to be no longer working.
>Only at 13:15, the instance receives the SIGTERM signal to shut itself down.
In the meantime a third JobManager is started 13:01. The third JobManager was
granted the leadership but it never starts the job.
I am suspecting that somewhere in
https://github.com/apache/flink/blob/release-1.12/flink-runtime/src/main/java/org/apache/flink/runtime/jobmaster/JobManagerRunnerImpl.java#L337
it fails.
Could you maybe run the deployment with DEBUG logs? This could help us further
pinning down the problem.
