Runping Qi commented on HADOOP-3327:
------------------------------------


Whoo, if  a map output cannot be fetched for some reason, it will take at least 
45minutes before the job tracker decides to re-execute the mapper?
That seems a really long time!


> Shufflinge fetachers waited too long between map output fetch re-tries
