Daniel Einspanjer commented on HBASE-1621:
------------------------------------------

Curious if the idea could be pushed even further and allow the merge to analyze the regions to find pairs to be merged, then specifically offline those regions and merge them rather than disabling the table..

> taking down the entire cluster to merge 2 regions is a pain, i dont see why the table or regions specifically couldnt be taken offline, then merged then brought back up.
> this might need a new API to the regionservers so they can take direction from not just the master.
