Esteban Gutierrez updated HBASE-15941:
--------------------------------------
Release Note: A new option -removeParents is now available that will remove
an old parent when two valid daughters for that parent exist and
-fixHdfsOverlaps is used. If there is an issue trying to remove the parent from
META or sidelining the parent from HDFS we will fallback to do a regular merge.
For now this option only works when the overlap group consists only of 3
regions (a parent, daughter A and daughter B)
> HBCK repair should not unsplit healthy splitted region

> Project: HBase
> Issue Type: Improvement
> Components: hbck
> Affects Versions: 1.0.0
> Reporter: 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.
