             Summary: HDFS delegation token is not being refreshed properly
                 Key: TWILL-106
                 URL: https://issues.apache.org/jira/browse/TWILL-106
             Project: Apache Twill
          Issue Type: Bug
          Components: core
    Affects Versions: 0.4.0-incubating
            Reporter: Poorna Chandra


We have a Twill app that runs in a secure Hadoop cluster. The app starts up fine, and runs for a day. I can see in logs that say secure store was updated regularly. However, after a day I see exceptions that say "token (HDFS_DELEGATION_TOKEN token 4287 for yarn) can't be found in cache". 

Exception:
-------------
