Daryn Sharp created YARN-60:
-------------------------------
Summary: NMs rejects all container tokens after 2nd secret key roll
Key: YARN-60
URL: https://issues.apache.org/jira/browse/YARN-60
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.2.0-alpha, 0.23.3
Reporter: Daryn Sharp
Assignee: Vinod Kumar Vavilapalli
Priority: Blocker
The NM's token secret manager will reject all container tokens after the third secret key
is activated which means the NM will not launch _any_ containers including AMs. The whole
yarn cluster becomes inoperable in 2d 15m (default 1d key roll + 15m activation delay).
The NM tracks the previous 2 secrets, so either the RM is generating tokens with an old secret,
or more likely the NMs are going out of sync when discarding the oldest secret.
