Subject [jira] [Created] (YARN-2790) NM can't aggregate logs past HDFS delegation token expiry.
Date Fri, 31 Oct 2014 19:12:34 GMT
Tassapol Athiapinya created YARN-2790:
-----------------------------------------

             Summary: NM can't aggregate logs past HDFS delegation token expiry.
                 Key: YARN-2790
                 URL: https://issues.apache.org/jira/browse/YARN-2790
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.6.0
            Reporter: Tassapol Athiapinya


We shorten hdfs delegation token lifetime, set RM to act as as a proxy user in order to be
able to renew the token on behalf of a user submitting the application. Still we see NM log
aggregation fail due to token expiry error.
