Subject [jira] [Updated] (HADOOP-13381) KMS clients running in the same JVM should use updated KMS Delegation Token
Date Mon, 18 Jul 2016 05:15:21 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13381?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiao Chen updated HADOOP-13381:
-------------------------------
    Description: 
When {{/tmp}} is setup as an EZ, one may experience YARN log aggregation failure after the
very first KMS token is expired. The MR job itself runs fine though.

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