Subject [jira] [Created] (HBASE-17383) Improve log msg when offheap memstore breaches higher water mark
Date Wed, 28 Dec 2016 10:14:58 GMT
ramkrishna.s.vasudevan created HBASE-17383:
----------------------------------------------

             Summary: Improve log msg when offheap memstore breaches higher water mark
                 Key: HBASE-17383
                 URL: https://issues.apache.org/jira/browse/HBASE-17383
             Project: HBase
          Issue Type: Improvement
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
            Priority: Trivial
             Fix For: 2.0.0


Currently we get this log
{code}
2016-12-28 21:11:14,349 INFO  [RpcServer.deafult.FPBQ.Fifo.handler=39,queue=9,port=16041]
regionserver.MemStoreFlusher: Blocking updates on stobdtserver5,16041,1482938527980: the global
offheap memstore size 12.6 G + global memstore heap overhead 4.0 G is >= than blocking
12.6 G size
{code}
Here the global offheap memstore size is greater than the blocking size. The memstore heap
overhead need not be included in this log unless the higher water mark breach is only due
to the heap overhead.
