Date Wed, 30 May 2012 07:15:22 GMT
Nishan Shetty created MAPREDUCE-4292:
----------------------------------------

             Summary: Job is hanging forever when some maps are failing always
                 Key: MAPREDUCE-4292
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4292
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.0.0-alpha
            Reporter: Nishan Shetty
            Priority: Critical


Set property "mapred.reduce.tasks" to some value greater than zero

I have a job in which some maps are failing always. 
Observations:
1.Map phase is completing with 100%(with succeeded and failed maps). 
2.Reduce phase is not progressing further after 32%.
3.After map phase is completed job is hanging forever.

Expected that job should be failed after waiting for some time.
