Subject [jira] [Created] (YARN-2371) Wrong NMToken is issued when NM preserving restart with containers running
Date Wed, 30 Jul 2014 06:46:38 GMT
Hong Zhiguo created YARN-2371:
---------------------------------

             Summary: Wrong NMToken is issued when NM preserving restart with containers running
                 Key: YARN-2371
                 URL: https://issues.apache.org/jira/browse/YARN-2371
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: Hong Zhiguo
            Assignee: Hong Zhiguo


When application is submitted with "ApplicationSubmissionContext.getKeepContainersAcrossApplicationAttempts()
== true", and NM is restarted with containers running, wrong NMToken is issued to AM through
RegisterApplicationMasterResponse.
See the NM log:
{code}
2014-07-30 11:59:58,941 ERROR org.apache.hadoop.yarn.server.nodemanager.containermanager.ContainerManagerImpl:
Unauthorized request to start container.-
NMToken for application attempt : appattempt_1406691610864_0002_000001 was used for starting
container with container token issued for application attempt : appattempt_1406691610864_0002_000002
{code}

The reason is in below code:
{code} 
createAndGetNMToken(String applicationSubmitter,
      ApplicationAttemptId appAttemptId, Container container) {
      ......
          Token token =
              createNMToken(container.getId().getApplicationAttemptId(),
                container.getNodeId(), applicationSubmitter);
     ......
}
{code} 
"appAttemptId" instead of "container.getId().getApplicationAttemptId()" should be passed to
"createNMToken".
