Prasanth Jayachandran commented on HIVE-16343:
----------------------------------------------
Removed all other options to find PID. Using JVM_PID approach suggested by
[~sseth]. Wrt. SMAP discussed with [~rajesh.balamohan], looks like it won't be
in the order of multiple seconds. Also NM metrics dumps meminfo every few
seconds (LLAP dump interval is even slower).
