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.
