-----------------------------------
Summary: HBASE_ZNODE_FILE on master server is overwritten by
regionserver process in case of master-rs collocation
Key: HBASE-14861
URL: https://issues.apache.org/jira/browse/HBASE-14861
Project: HBase
Issue Type: Bug
Components: Operability
Affects Versions: 2.0.0
Reporter: Samir Ahmic
Assignee: Samir Ahmic
In case of master-rs collocation HBASE_ZNODE_FILE is overwritten by
regionserver process in HRegionServer#handleReportForDutyResponse() here is how
it looks on master server:
{code}
[hbase@hnode2 hbase]$ cat hbase-hbase-master.znode
/hbase/rs/hnode2,16000,1448022074888
{code}
it contains regionserver znode path instead of String value of master's
ServerName. This affects ZNodeClearer#clear() in way that will not clear
master znode in case we detect master crash. At end this will extend failover
time until master znode expires configured in zookeeper by maxSessionTimeout
parameter (40s in my case).
I have notice this on mater branch but it can be case in other branches where
we are collocating master and rs.
