-----------------------------

             Summary: yarnClient should be closed in AbstractYarnClusterDescriptor for error conditions
                 Key: FLINK-5488
                 URL: https://issues.apache.org/jira/browse/FLINK-5488
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu


Here is one example:
{code}
    if(jobManagerMemoryMb > maxRes.getMemory() ) {
      failSessionDuringDeployment(yarnClient, yarnApplication);
      throw new YarnDeploymentException("The cluster does not have the requested resources for the JobManager available!\n"
        + "Maximum Memory: " + maxRes.getMemory() + "MB Requested: " + jobManagerMemoryMb + "MB. " + NOTE);
    }
{code}
yarnClient implements Closeable.
It should be closed in situations where exception is thrown.
