[jira] [Created] (TWILL-175) Hadoop21YarnAppClient caches a YarnClient

Ali Anwar created TWILL-175:
-------------------------------

             Summary: Hadoop21YarnAppClient caches a YarnClient
                 Key: TWILL-175
                 URL: https://issues.apache.org/jira/browse/TWILL-175
             Project: Apache Twill
          Issue Type: Bug
    Affects Versions: 0.7.0-incubating
            Reporter: Ali Anwar
             Fix For: 0.8.0


Hadoop21YarnAppClient caches a YarnClient.
Internally, YarnClient is only useful for a single UserGroupInformation. Because of this, you can not use the same Hadoop21YarnAppClient for multiple UGIs.
The Hadoop21YarnAppClient class should use a different YarnClient for each UGI.
