Hi Experts   I was trying to do simlilar change i.e. change Java option manually, however my problem is bit different.  I need to reduce value of parameter "Java Heap Size of HBase RegionServer in Bytes"  - only on 1 region server because this host has less memory allocated compare to others.  I want this parameter to be in effect  only for one host but region server role consistes of 3 hosts     Thanks in advance ...
