Cluster with too many regions cannot withstand some master failover scenarios

      Description

      We ran into the following sequence of events:

      • master startup failed after only ROOT had been assigned (for another reason)
      • restarted the master without restarting other servers. Since there was at least one region assigned, it went through the failover code path
      • master scanned META and inserted every region into /hbase/unassigned in ZK.
      • then, it called "listChildren" on the /hbase/unassigned znode, and crashed with "Packet len6080218 is out of range!" since the IPC response was larger than the default maximum.
