      Description

      When running a single flink job on YARN, some of the taskmanger containers reach the FINISHED state before others.  It appears that, after receiving final execution state FINISHED from a taskmanager, jobmanager is waiting ~68 seconds and then freeing the associated slot in the taskmanager.  After and additional 60 seconds, jobmanager is stopping the same taskmanger because TaskExecutor exceeded the idle timeout.

      Meanwhile, other taskmangers are still working to complete the job.  Within 10 seconds after the taskmanger container above is stopped, the remaining task managers receive an exception due to loss of connection to the stopped taskmanager.  These exceptions result job failure.
