Niklas Semmler commented on FLINK-24960:
----------------------------------------
An early analysis.
# We start the JobManager via YARN - Works
# We identify the address of the REST server - We get the right address
# We start a RestClient to submit a job via YARN - Works
# RestClusterClient tries to submit job
In the last step, a default address "localhost:8081" is used instead of the
correct external address port combination. This leads to a connection refused
error. I am not sure why this happens though. From how I understand
{{RestClusterClient#sendRetriableRequest}}, it tries to get the address by
using web monitor leader retrieval. It doesn't make sense to me, why this would
return localhost:8081. I also don't see any place where this could fallback to
the localhost:8081 pair.
