Hello, I have given a case where my mapper should fail. That is, based on a result it throws an exception if(res==0) throw new IOException("Error in code!, see stderr/out"); , When i go to the JobTracker website, e.g http://tracker.com:50030/jobdetails.jsp?jobid=job_200903051709_0024&refresh=30 and click on one of the running tasks, I see an IOException in the errors column. But on the jobtracker page for the job, it doesn't fail - it stays in the running column , never moving to the failed/killed columns (not even after 10 minutes)
Why so? Regards Saptarshi Guha
