Date Thu, 01 Sep 2016 14:54:20 GMT
Subroto Sanyal created TEZ-3424:
-----------------------------------

             Summary: Yarn trying to renew token as user 'nobody'
                 Key: TEZ-3424
                 URL: https://issues.apache.org/jira/browse/TEZ-3424
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.6.1
            Reporter: Subroto Sanyal


Tez jobs are failing with the exception:
{noformat}Caused by: org.apache.tez.dag.api.TezException: Failed to submit application to
YARN, applicationId=application_1471954345692_0109, diagnostics=Failed to renew token: Kind:
HDFS_DELEGATION_TOKEN, Service: ha-hdfs:datalab-dev, Ident: (HDFS_DELEGATION_TOKEN token 34599
for veshikh)
	at org.apache.tez.client.TezYarnClient.submitApplication(TezYarnClient.java:75)
	at org.apache.tez.client.TezClient.start(TezClient.java:365){noformat}

On the namenode side there is warn log
{noformat}209387 2016-08-24 13:43:03,305 WARN org.apache.hadoop.security.UserGroupInformation:
PriviledgedActionException as:yarn/somehost.ec2.internal@EC2.INTERNAL (auth:KERBEROS) cause:org.apache.hadoop.security.AccessControlException:
yarn tries to renew a token with renewer nobody
{noformat}

This looks very similar to MAPREDUCE-6484 and upon looking into the code of {{org.apache.tez.common.security.Master}}
shows the same issue.
