ramkrishna.s.vasudevan commented on HBASE-10137:
------------------------------------------------
As this is fixed in Trunk this change should be fine.
+1 for being only on trunk.
One quesiton is
bq.In case of any failures retrying assignments and wait in
GeneralBulkAssigner#waitUntilDone.
Yes this would happen now.
But after disabled had happened before enabling, if a REgion server goes down
and going with retainAssignment? how would this work?
META may have the dead RS entry but the servermanager won't be giving the old
ones. Will this be handled here?
> GeneralBulkAssigner with retain assignment plan can be used in
> EnableTableHandler to bulk assign the regions
