> *(1). Use the correct value for Node(s) used for running LLAP Daemon(s).*
> - *Existing :* While starting LLAP, it was not taken into account removing the Nodes
used for SLider and Tez AM from 'num_llap_nodes' value, before using it for starting LLAP
by passing 'num_llap_nodes''s value to --instances parameter.
> - *Fix:* Introduced new config 'num_llap_nodes_for_llap_daemons' which has the updated
value substracting the nodes used by Tez and SLider AM's.
> *(2). Set 'num_llap_nodes' calculated value only for non Ambari managed queue.*
> *Fix:* With AMBARI-19814 patch, UI shows 'num_llap_nodes' slider as READ only for non
Ambari managed queue for LLAP. We will be setting the calculated 'num_llap_nodes' slider value
only for non-Ambari managed queue. For Ambari managed queue named 'llap', user has the liberty
of entering the value. We may end up using less nodes than that, as part of calculation, but
we dont want to override the User entered value.
