[jira] [Created] (HBASE-5566) [89-fb] Region server can get stuck
getMaster on master failover
[89-fb] Region server can get stuck getMaster on master failover
----------------------------------------------------------------
Key: HBASE-5566
URL: https://issues.apache.org/jira/browse/HBASE-5566
Project: HBase
Issue Type: Bug
Affects Versions: 0.89-fb
Reporter: Mikhail Bautin
Assignee: Mikhail Bautin
Reported by Prakash. We have a retry loop in HRegionServer.getMaster where we do not read the location of the master from ZK, so a region server can get stuck there on master failover. We need to add a unit test to reliably catch this, and fix the bug.
