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
> JobClient.getJob(JobID) broken in 0.23 for LocalJobRunner?
