Esteban Gutierrez commented on HBASE-15941:
-------------------------------------------
Hi [~syuanjiang], can you take a look to this approach? Basically if we are
100% sure that there is parent is present and the splits are valid daughters
then we remove the parent and sideline the parent. Otherwise we fallback to the
current approach. Thanks!
> HBCK repair should not unsplit healthy splitted region

> 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.
