Jean-Daniel Cryans updated HBASE-1621:
--------------------------------------
Attachment: HBASE-1621-v2.patch
Patch that actually only merges the specified table.
After fixing it I tried it on a cluster, shaved off around 350 regions on a big
table in about 8 minutes.
> merge tool should work on online cluster, but disabled 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.
