> Currently when stopping Hive server interactive, the following steps seem to
> be taken.
> 1. Send kill to hive server interactive process
> 2. Wait for 5 seconds and send kill -9 if process in not killed.
> If HS2 is not shutdown properly - long running sessions (AMs) started by it
> will not be killed. In case of LLAP - these sessions will typically run for
> hours. Without the kill - LLAP cannot be restarted, since the old sessions
> will exist in the LLAP queue, and due to the precise capacity calculations -
> the queue will not have enough capacity to start new sessions.
> Ideally it should wait for 30 second before sending kill -9
