Subject APEXCORE-294 Clean application shutdown
Date Fri, 25 Nov 2016 11:10:19 GMT
Dear Community,

I have open an pull request for shutting down application by sending
END_STREAM control tuples from all input operator. This is similar to
all input operator have stopped after raising ShutdownException.

On receiving shutdown request, master will prepare OPERATOR_STOP
command for all input partitions, and send it to container as part of
heartbeat response to container. Container will shutdown the operator
thread after receiving this command.

Please review.
