["Edward J. Yoon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HAMA-848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14291494#comment-14291494 ] 

Edward J. Yoon commented on HAMA-848:
-------------------------------------

If you recevies the NullPointerException error, Please try like this:

{code}
     ClusterStatus clusterStatus = getClusterStatus(true);
    
    int maxTasks = job.getConfiguration().getInt(Constants.MAX_TASKS, 0);
    if (clusterStatus != null) {
      maxTasks = job.getConfiguration().getInt(Constants.MAX_TASKS_PER_JOB,
          clusterStatus.getMaxTasks() - clusterStatus.getTasks());
    }
{code}

Of course, this is not full solution. For the testing.

> Current yarn-module was implemented based on Hadoop 0.23.1 version. You'll need to use the Hama RPC instead of Hadoop RPC.
