-----------------------------------

             Summary: Uninformative message in HRegionServer
                 Key: HBASE-13452
                 URL: https://issues.apache.org/jira/browse/HBASE-13452
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 1.0.0
            Reporter: Dev Lakhani


During normal operation the HRegion class reports a message related to memstore flushing in HRegion.class :

      if (!canFlush) {
        addAndGetGlobalMemstoreSize(-memstoreSize.get());
      } else if (memstoreSize.get() != 0) {
        LOG.error("Memstore size is " + memstoreSize.get());
      }

The log file is filled with lots of 

Memstore size is: 190192
Memstore size is: 442232
Memstore size is: 190192
...

These message are uninformative, clog up the logs and offers no root cause nor solution. Maybe the message needs to be more informative, changed to WARN or some further information provided.
