Subject [jira] [Created] (HBASE-18694) Ha mode master switch causes region not online
Date Sat, 26 Aug 2017 02:10:00 GMT
Bo Cui created HBASE-18694:

             Summary: Ha mode master switch causes region not online
                 Key: HBASE-18694
                 URL: https://issues.apache.org/jira/browse/HBASE-18694
             Project: HBase
          Issue Type: Bug
          Components: master, Zookeeper
    Affects Versions: 0.98.10
            Reporter: Bo Cui

HA mode has two master, firstMaster and secondMaster; at the beginning, SecondMaster is active,
firstMaster is standby.
After secondMaster sends the openregion  request to rs , the rs begins to launch regions,
and the secondMaster just happened to be arbor; firstMaster becomes active and receives the
zk message (node changed opend), but the region state in firstMaster memory is not opening,
firstMaster sends the send closeRegion to rs, the region will never be on-line.
Other versions should also exist the problem.
