Subject [jira] [Created] (YARN-4414) Nodemanager connection errors are retried at multiple levels
Date Thu, 03 Dec 2015 17:02:11 GMT
Jason Lowe created YARN-4414:
--------------------------------

             Summary: Nodemanager connection errors are retried at multiple levels
                 Key: YARN-4414
                 URL: https://issues.apache.org/jira/browse/YARN-4414
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.6.2, 2.7.1
            Reporter: Jason Lowe


This is related to YARN-3238.  Ran into more scenarios where connection errors are being retried
at multiple levels, like NoRouteToHostException.  The fix for YARN-3238 was too specific,
and I think we need a more general solution to catch a wider array of connection errors that
can occur to avoid retrying them both at the RPC layer and at the NM proxy layer.
