[jira] [Created] (FLINK-8505) SlotManager can reach inconsistent state

Till Rohrmann created FLINK-8505:
------------------------------------

             Summary: SlotManager can reach inconsistent state
                 Key: FLINK-8505
                 URL: https://issues.apache.org/jira/browse/FLINK-8505
             Project: Flink
          Issue Type: Bug
          Components: Distributed Coordination
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.0


The {{SlotManager}} can reach an inconsistent state when a formerly free task slot is reported as allocated by an incoming {{SlotReport}}. The problem is that the slot won't be removed from the set of free slots and, thus, will be considered for future slot requests.

The solution is to remove the slot from the set of free slots once it is reported allocated.
