Subject [jira] [Created] (HBASE-5939) Add an autorestart option in the start scripts
Date Fri, 04 May 2012 16:28:49 GMT

------------------------------

             Summary: Add an autorestart option in the start scripts
                 Key: HBASE-5939
                 URL: https://issues.apache.org/jira/browse/HBASE-5939
             Project: HBase
          Issue Type: Improvement
          Components: master, regionserver, scripts
    Affects Versions: 0.96.0
            Reporter: nkeywal
            Assignee: nkeywal
            Priority: Minor


When a binary dies on a server, we don't try to restart it while it would be possible in most
cases.

We can have something as:
loop
 start
 wait
 if cleanStop then exit
 if already stopped less than 5 minutes ago sleep 1 minute
endloop

This is simple for master & backup master, a little bit more complex for the region server
as it can be stopped by a script or by the shutdown procedure.

On a long long term it could allow a restart with exactly the same assignments.
