------------------------------------
Summary: Make job submission retriable operation in case of a
ongoing leader election
Key: FLINK-9416
URL: https://issues.apache.org/jira/browse/FLINK-9416
Project: Flink
Issue Type: Bug
Components: Client
Affects Versions: 1.5.0, 1.6.0
Reporter: Till Rohrmann
When starting a session cluster, it can happen that the job submission fails if
the REST server endpoint has already gained leadership but if the leadership
election for the {{Dispatcher}} is still ongoing. In such a case, we receive a
error response saying that the leader election is still ongoing and fail the
job submission. I think it would be nicer to also make the submission step a
retriable operation in order to avoid this race condition.
