Steve Loughran created YARN-9109: ------------------------------------ Summary: DelegationTokenRenewer not resilient to token classload problems Key: YARN-9109 URL: https://issues.apache.org/jira/browse/YARN-9109 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 3.1.2 Reporter: Steve Loughran
The DelegationTokenRenewer can't handle the situation of: token implementation class cannot be instantiated. This is because {{Token.decodeIdentifier()}} throws an RTE on failure to instantiate, and these aren't caught. Appears to surfaces in the client: with an error about "Timer Already Cancelled". In the logs, you see this {code} Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "Timer-5" {code} At least, I'm assuming this is the cause....
