> Internally we have a cluster of thousands of regions.  We just did a hbase restart w/ master on new node.  Just so happened that one of the regionservers was running extra slow (was downloaded by other processes).  Meant that its portion of the assigments was taking a long time to come up...  While these regions were stuck in deploy mode, the cluster is not useable.
> We need a sort of 'safe-mode' in hbase where clients fail if they try to attach to a cluster not yet fully up.  UI should show when all assignments have been successfully made so admin can at least see when they have a problematic regionserver in their midst.
