----------------------------------
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.
