Subject Reduce copy speed too slow
Date Tue, 20 Mar 2012 15:59:08 GMT
Hi all,

I am running a map reduce job in EC2 instances and it seems to be very
slow. It takes hours together for simple projection and aggregation of
data.
Upon observation, I gathered that the reduce copy speed is 0.01 MB/sec. I
am new to hadoop. Could any one please share  insights about the reduce
copy speeds
are good to work with. If any one has an experience any tips in improving
it.

Thanks
Gayatri
