Swapan Shridhar updated AMBARI-15876:
-------------------------------------
Description:
--> When Hive Server Interactive is turned ON:
===================================
Ambari creates OR "modifies 'llap' queue 'state and/or capacity' " based on
below conditions:
- if only 1 queue exists at root level and is 'default' queue and has
100% cap -> Creates 'llap' queue, OR
- if 2 queues exists at root level ('llap' and 'default') :
-> 'llap' queue state is STOPPED -> Modifies 'llap' queue state to
RUNNING, adjusts capacity, OR
-> 'llap' queue state is RUNNING and 'llap_queue_capacity' prop !=
'llap' queue current running capacity ->
Modifies 'llap' queue capacity to 'llap_queue_capacity'.
--> When Hive Server Interactive is turned OFF:
===================================
- Checks and sees (1). If only two leaf queues exist at root level,
namely: 'default' and 'llap',
and (2). 'llap' is in RUNNING state.
- If yes, performs the following actions: (1). 'llap' queue state set
to STOPPED,
(2). 'llap' queue capacity set
to 0 %,
(3). 'default' queue capacity
set to 100 %
