Subject [jira] [Created] (YARN-342) RM doesn't retry token renewals
Date Tue, 15 Jan 2013 15:22:12 GMT
Daryn Sharp created YARN-342:
--------------------------------

             Summary: RM doesn't retry token renewals
                 Key: YARN-342
                 URL: https://issues.apache.org/jira/browse/YARN-342
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.6
            Reporter: Daryn Sharp


The RM stops trying to renew tokens if any exception occurs during the renew.  This should
be changed to abort only if the exception is {{InvalidToken}} to allow resilience to transient
network failures, issues associated with aborted connections when the NN is overloaded, cluster
upgrades, etc.
