Vincent Poon commented on PHOENIX-4990:
---------------------------------------
[~gjacoby] The check immediately after await() is checking the executor for #
of active threads, not the numAttempts counter.
Runner.stop() is should wait for the thread to finish (after an interrupt). If
the thread finishes, then the numAttempts should be 1 after stop().
> When stopping IndexWriter, give tasks a chance to complete

> We've seen a race condition where an index write failure happens when a
> coprocessor is shutting down. Since we don't give the index writer threads a
> chance to complete when shutdownNow() is called, there is a chance the
> coprocessor shuts down its HTables while an index writer thread is in
> PhoenixIndexFailurePolicy trying to disable an index, which ends up using a
> closed HTable and received RejectedExecutionException
