> 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.
