Gopinathan A created HBASE-6046:
-----------------------------------
Summary: Master retry on ZK session expiry causes inconsistent
region assignments.
Key: HBASE-6046
URL: https://issues.apache.org/jira/browse/HBASE-6046
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.94.0, 0.92.1
Reporter: Gopinathan A
Fix For: 0.92.2, 0.94.1
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.
