             Summary: Master log start filling with "Flush journal status" messages
                 Key: HBASE-23668

            Reporter: Michael Stack
             Fix For: 2.3.0


Takes a while to get into this condition. Not each to tell how because all logs have rolled off and I only have logs filled w/ below:

{code}
2020-01-09 07:01:01,723 DEBUG org.apache.hadoop.hbase.regionserver.HRegion: Flush status journal:
	Acquiring readlock on region at 1578553261723

	Flush successful flush result:CANNOT_FLUSH_MEMSTORE_EMPTY, failureReason:Nothing to flush,flush seq id45226857 at 1578553261723
{code}

... I added the printing of flushresult... i.e. cannot flush because store is empty.

Digging.
