Description

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
