--------------------------------
Summary: RM renews tokens even when maxDate will soon be exceeded
Key: YARN-338
URL: https://issues.apache.org/jira/browse/YARN-338
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.3
Reporter: Daryn Sharp
The RM will renew tokens 90% of the way to the next expiration. When the max
lifetime is approaching, the next expiration is always the max lifetime. The
RM starts to unnecessarily renew more and more frequent as that hard limit
approaches. The RM should stop renewing when the last expiration matches the
new expiration.
