Lars Hofhansl commented on HBASE-4991:
--------------------------------------
I have not been following this too closely, so pardon my ignorance... But it
seems we're going off in a tangent.
This is not the same as merge, right? The region's data will be gone, we just
need to plug the .META. hole (hbck, could even do that for us).
Or maybe we don't even touch .META. and just delete the DFS files.
1. close/unassign the region
2. remove the region's files
3. either
o re-open the region, i.e. keep the .META. entry for the empty region, and
merge later when convenient
or
o remove the region's .META. entry
4. done :)
Maybe I'm just talking nonsense, but does it have to be much more complicated
than this?
