Anoop Sam John commented on HBASE-16421:
----------------------------------------
Use the new config 'hbase.regionserver.offheap.global.memstore.size' which says
the global off heap memstore size. (Size in MBs) We still need
'hbase.regionserver.global.memstore.size' also which says the heap % for max
global size. Also to make sure that the system using MSLAB and pool.
hbase.hregion.memstore.mslab.enabled -> True
hbase.hregion.memstore.chunkpool.maxsize -> 1 These configs def value only
Also pls make sure that HBASE_OFFHEAPSIZE is having appropriate value
(hbase-env.sh).. Need to add some more than the global off heap memstore
size (Like 2 GB or so). The ByteBufferPool at RPC layer uses off heap memory.
Also the NIO layer need some off heap memory as well.
