> 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.
