Description

YarnClientProtocolProvider creates YarnRunner which includes ResourceMgrDelegate. In ResourceMgrDelegate, we would initiate and start yarnclient. The yarnClient thread would be leaked due to

  @Override
  public void close(ClientProtocol clientProtocol) throws IOException {
    // nothing to do
  }

in YarnClientProtocolProvider
