Description

We found this log in our master.

2018-10-26,10:00:00,449 INFO [master/c4-hadoop-tst-ct16:42900:becomeActiveMaster] org.apache.hadoop.hbase.regionserver.ChunkCreator: Allocating data MemStoreChunkPool with chunk size 2 MB, max count 737, initial count 0
2018-10-26,10:00:00,452 INFO [master/c4-hadoop-tst-ct16:42900:becomeActiveMaster] org.apache.hadoop.hbase.regionserver.ChunkCreator: Allocating index MemStoreChunkPool with chunk size 204.80 KB, max count 819, initial count 0

 

Same with HBASE-21290, we don't need to instantiate MemStore for master which not carry table.
