Guanghao Zhang commented on HBASE-21388: ---------------------------------------- The MemStoreLAB and ChunkCreator is global per process. The minicluster start master and rs in same process, the ut will failed as rs will create a new MemStoreLAB. Will find a way to resolve this later. > No need to instantiate MemStoreLAB 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 > Assignee: Guanghao Zhang > Priority: Major > Attachments: HBASE-21388.master.001.patch > > > 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. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
