Subject [jira] [Created] (HBASE-8102) Replication NodeFailoverWorker should check other rs znodes before proceeding
Date Thu, 14 Mar 2013 05:44:14 GMT
Himanshu Vashishtha created HBASE-8102:
------------------------------------------

             Summary: Replication NodeFailoverWorker should check other rs znodes before proceeding
                 Key: HBASE-8102
                 URL: https://issues.apache.org/jira/browse/HBASE-8102
             Project: HBase
          Issue Type: Improvement
          Components: Replication
    Affects Versions: 0.94.5
            Reporter: Himanshu Vashishtha
            Assignee: Himanshu Vashishtha
             Fix For: 0.95.0, 0.94.7


NodeFailoverWorker takes the dead rs znode and starts processing it (moving the log znodes
under it, etc). 
Even a regionserver restart will trigger this znodes movement. This cause some other regionserver
to read the log files remotely, even though, the original regionserver is up. Ideally, it
should check available regionserver znodes after it comes out it sleep in its run method in
order to decide whether it should really process the znode or not.
