> Components: master
> Affects Versions: 0.92.1, 0.94.0
> Reporter: Gopinathan A
> Assignee: ramkrishna.s.vasudevan

>
> 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.
