Daryn Sharp created YARN-342:
--------------------------------
Summary: RM doesn't retry token renewals
Key: YARN-342
URL: https://issues.apache.org/jira/browse/YARN-342
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.6
Reporter: Daryn Sharp
The RM stops trying to renew tokens if any exception occurs during the renew.
This should be changed to abort only if the exception is {{InvalidToken}} to
allow resilience to transient network failures, issues associated with aborted
connections when the NN is overloaded, cluster upgrades, etc.
