stack commented on HBASE-22709:
-------------------------------
bq. I thought we only fix it by HBCK2 now... The master UI shows the orphan
regions and user use HBCK2 to fix them.
HBCK2 will ask the Master to adopt 'orphans', yes. This facility will find the
orphans. We maybe should make it so HBCK2 can ask the Master for list of
orphans (JSON listing?)
> Add a chore thread in master to do hbck checking

> See HBASE-21965. There may have two type of failed splited/merged regions.
> One is orphan region on filesystem. Another one is unassigned daughter
> regions or merged regions. Plan to add a seperate hbck.jsp for them. Will add
> more hbck problems to this UI in future.
