["Amareshwari Sriramadasu (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13188946#comment-13188946 ] 

Amareshwari Sriramadasu commented on MAPREDUCE-3694:
----------------------------------------------------

I suspect the problem is with following:
0.20.20x code :
{noformat}
public JobStatus getJobStatus(JobID id) {
    Job job = jobs.get(id);
    if(job != null)
      return job.status;
    else 
      return null;
  }
{noformat}

{noformat}
 public org.apache.hadoop.mapreduce.JobStatus getJobStatus(
      org.apache.hadoop.mapreduce.JobID id) {
    Job job = jobs.get(JobID.downgrade(id));
    if(job != null)
      return job.status;
    else 
      return null;
  }
{noformat}

so Mostly, Looking into jobs through JobID.downgrade(id) might be causing the problem
