[jira] [Created] (HBASE-11430) lastFlushSeqId has been updated wrongly during region open

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

             Summary: lastFlushSeqId has been updated wrongly during region open
                 Key: HBASE-11430
                 URL: https://issues.apache.org/jira/browse/HBASE-11430
             Project: HBase
          Issue Type: Bug
          Components: MTTR
    Affects Versions: 0.98.3, 0.99.0
            Reporter: Jeffrey Zhong
            Assignee: Jeffrey Zhong


In HRegion this.lastFlushSeqId is updated when opening a region which is wrong and will cause issue in distributedLogReplay recovery mode(not in log splitting mode) because its value is bumped up for log replay mode. 

This may cause data loss issue when we recover a region in distributedLogReplay mode while no flush for the region because no edits to be replayed. Later the region move to another region server and then future recovery will have issue because the large flush sequence Id value.
