Subject: Re: How to balance reduce job
Hi Rauljin
Few things to check here.
What is the number of reduce slots in each Task Tracker? What is the number of
reduce tasks for your job?
Based
8 datanode in my hadoop cluseter ,when running reduce job,there is only 2
datanode running the job .
I want to use the 8 datanode to run the reduce job,so I can balance the I/O
press.
Any ideas?
Thanks.

what causes the problem.
Any ideas?
Thanks!
