Daryn Sharp created YARN-320:
--------------------------------
Summary: RM should always be able to renew its own tokens
Key: YARN-320
URL: https://issues.apache.org/jira/browse/YARN-320
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 3.0.0, 2.0.3-alpha, 0.23.6
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Priority: Blocker
YARN-280 introduced fast-fail for job submissions with bad tokens.
Unfortunately, other stack components like oozie and customers are acquiring RM
tokens with a hardcoded dummy renewer value. These jobs would fail after 24
hours because the RM token couldn't be renewed, but fast-fail is failing them
immediately. The RM should always be able to renew its own tokens submitted
with a job. The renewer field may continue to specify an external user who can
renew.
