> 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.
