stack commented on HBASE-3756:
------------------------------
Let me see if I can come up w/ a unit test to go w/ the patch....
I got into this scenario when a but in rolling restart crashed the master. I
brought master back online and then reran rolling restart. It ran fine till it
came to the .META. region.... then fell into a loop of trying to move but
failing.
> Can't move META or ROOT from shell
