             Summary: No need to instantiate MemStore for master which not 
carry table
                 Key: HBASE-21388
                 URL: https://issues.apache.org/jira/browse/HBASE-21388
             Project: HBase
          Issue Type: Improvement
            Reporter: Guanghao Zhang


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.
