Chesnay Schepler commented on FLINK-11835:
------------------------------------------
I'm still somewhat working on it. I checked out Florian's branch and could
reproduce one instance of the problem.
What seemed to happen is that the slot allocation fails on one of the first
dispatchers, resulting in a failure of the job. Given that we shutdown the
ResourceManager in the test it kinda makes sense that this can happen. The job
was marked as done in ZK, and subsequent dispatchers never recovered the job,
hence the job status can not be queried later.
The exact underlying cause for the RM shutdown usually resulting in a JM
failover, but sometime in a job failure, is still unknown.
