ramkrishna.s.vasudevan commented on HBASE-6046:
-----------------------------------------------
I think its better to do finishInitialization step fully. Ashutosh and myself
saw problems in the current way of handlng
-> MAster not knowing that a RS has gone down.
-> So no split happens
-> So we need to do all the steps in finish initialization.
-> We tried to do all the steps from waitForRegionServers till the end, but
here again the masterfilesystem is initializing the splitlogmanager.
So can we call finish initialization itself once again?
> Master retry on ZK session expiry causes inconsistent region assignments.

> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.92.1, 0.94.0
> Reporter: Gopinathan A

> 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.
