[jira] [Created] (HBASE-15941) HBCK repair should not unsplit healthy splitted region

Stephen Yuan Jiang created HBASE-15941:
------------------------------------------

             Summary: HBCK repair should not unsplit healthy splitted region
                 Key: HBASE-15941
                 URL: https://issues.apache.org/jira/browse/HBASE-15941
             Project: HBase
          Issue Type: Improvement
          Components: hbck
    Affects Versions: 1.0.0
            Reporter: Stephen Yuan Jiang
            Assignee: Stephen Yuan Jiang


Currently HBCK design in branch-1 has a flaw when repair option (the -fixHdfsOverlaps option specifically) is specified: it would wrongly merge split region (by looking at HDFS, it thinks that there exists overlapped regions - parent region and daughter regions covers the same key range, of course).  See HBASE-15940 for details.  

This JIRA tracks the improvement not-to-merge split region in HBCK repair.
