> 1> ZK Session timeout in the hmaster leads to bulk assignment though all the RSs are online.
> 2> While doing bulk assignment, if the master again goes down & restart(or backup comes up) all the node created in the ZK will now be tried to reassign to the new RSs. This is leading to double assignment.
> we had 2800 regions, among this 1900 region got double assignment, taking the region count to 4700.
