Jonathan Hsieh commented on HBASE-4991:
---------------------------------------
Oops -- wasn't looking at the comment tab.
There is similar code in OnlineMerge and uber hbck.
The code in uber hbck creates a new empty region, closes old regions, moves
data into the new empty region, and then activates the new now populated region.
Beware -- I found just closing a region seems to have left data around in the
HMaster's memory which cause disabling to have problems in the 0.90.x version.
I'm in the process of porting to trunk/0.92 currently and am finding out if
there are similar or different problems. I think I saw something else in
closeRegion recently that I need to try out -- don't remember which version
that is however.
