----------------------------------
Summary: Early slot release after Execution failure
Key: FLINK-2110
URL: https://issues.apache.org/jira/browse/FLINK-2110
Project: Flink
Issue Type: Bug
Components: Scheduler
Affects Versions: master
Reporter: Ufuk Celebi
In {{Execution#processFail(Throwable, boolean)}}, the slot is released before
the cancel msg is send to the respective task manager assigned to this
Execution.
Cancelling on the TM can take some time, which can result in a too early
release of the slot on the JM.
