Sergey Shelukhin updated HIVE-12939:
------------------------------------
Description: When one of the default queues is fully used, or not sized
correctly, the corresponding pool sessions may not be able to start in a timely
manner (or at all), and HS2 startup would hang forever. Need to add a timeout
around that (in Hive for now, since Tez does not have the APIs that we need).
