Subject [jira] [Created] (HADOOP-13381) KMS clients running in the same JVM should use updated KMS Delegation Token
Date Fri, 15 Jul 2016 22:29:20 GMT
Xiao Chen created HADOOP-13381:
----------------------------------

             Summary: KMS clients running in the same JVM should use updated KMS Delegation
Token
                 Key: HADOOP-13381
                 URL: https://issues.apache.org/jira/browse/HADOOP-13381
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
    Affects Versions: 2.6.0
            Reporter: Xiao Chen
            Assignee: Xiao Chen
            Priority: Critical


When {{/tmp}} is setup as an EZ, one may experience YARN log aggregation failure after the
KMS token is expired. The MR job itself runs find though.

When this happens, YARN NodeManager's log will show {{AuthenticationException}} with token
is expire / token can't be found in cache, depending on whether the expired token is removed
by the background or not.
