-------------------------------------
    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 %
