Subject A small portion of map tasks slows down the job
Date Wed, 03 Oct 2012 01:04:16 GMT
Hello,

I have a small portion of map tasks whose output is much larger than others (more spills).
So the reducer is mainly waiting for these a few map tasks. Is there a good solution for this
problem ?

Thank you.

Best,
Huanchen
