Data local map tasks is zero

Hi,

I have a 3 node cluster with dfs replication factor as 3. I have a single sequence file over which I am running a map reduce job. When I run my job, web UI shows data local map tasks as zero out of total 333 map tasks. I feel this is pulling down the performance. Am I right? If yes, what should I check to fix this issue. Thanks for any assistance.

Regards,
Anand.C
