Multiple reduce task retries running at same time
Hi!

I have come across the situation where i found a single reducer task
executing with multiple retries simultaneously.
Which is potent for slowing down the whole reduce process for large data
sets.

Is this pretty normal to yall for hadoop 1.0.3?
