Xuan Gong created MAPREDUCE-6618:
------------------------------------

             Summary: YarnClientProtocolProvider leaking the YarnClient thread. 
                 Key: MAPREDUCE-6618
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6618
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Xuan Gong
            Assignee: Xuan Gong


YarnClientProtocolProvider creates YarnRunner which includes ResourceMgrDelegate. In ResourceMgrDelegate, we would initiate and start yarnclient. The yarnClient thread would be leaked due to
{code}
  @Override
  public void close(ClientProtocol clientProtocol) throws IOException {
    // nothing to do
  }
{code} in YarnClientProtocolProvider
