             Summary: RM behaviour on token renewal failures is broken
                 Key: YARN-2836
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli
            Priority: Blocker

Found this while reviewing YARN-2834.

We now completely ignore token renewal failures. For things like Timeline 
tokens which are automatically obtained whether the app needs it or not (we 
should fix this to be user driven), we can ignore failures. But for HDFS Tokens 
etc, ignoring failures is bad because it (1) wastes resources as AMs will 
continue and eventually fail (2) app doesn't know what happened it fails
