HBase RegionServer heap size
Post transition to CDP Private Cloud Base 7.1.7 SP2, you must adjust the HBase RegionServer heap size.
The change introduced in HBASE-26036/HBASE-26777 adds an extra copy of cells into the heap, resulting in out of memory on the region servers if the hbase_regionserver_java_heapsize is not set correctly. Also, if the region server is killed because of out of memory issue under a large amount concurrent PUTs with multi-columns and scan the recent result. This issue accours only during the two stage upgrade from HDP 2.6.5 to CDP Private Cloud Base 7.1.7 SP2.
