fulin wang commented on HBASE-4124:
-----------------------------------

I can't find where does it call getRegionsInTransitionInRS().add()? So I do not understand
why add this function.
About 'already online on this server' of error, I want that the region should be closed or
reassinged. I am trying to make a patch.
