Swapan Shridhar updated AMBARI-19971:
-------------------------------------
Description:
*(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.
