Heng Chen commented on HBASE-14803:
-----------------------------------
Oh, the patch will cause
org.apache.hadoop.hbase.regionserver.TestRecoveredEdits timeout!
Maybe that is why there is NO logs in StoreFileScanner, it dumps too many....
{code}
testReplayWorksThoughLotsOfFlushing(org.apache.hadoop.hbase.regionserver.TestRecoveredEdits)
Time elapsed: 60.083 sec <<< ERROR!
org.junit.runners.model.TestTimedOutException: test timed out after 60000
