Subject [jira] [Updated] (MAPREDUCE-3070) NM not able to register with RM after NM restart
Date Mon, 10 Oct 2011 04:48:29 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-3070:
-----------------------------------------------

          Component/s: nodemanager
    Affects Version/s: 0.23.0
        Fix Version/s: 0.23.0

We need this for 0.23, setting the Fix-version.

This should be done together with MAPREDUCE-3034. We need RM side changes to help duplicate
registration. And NM side changes described at MAPREDUCE-3034.
