Duplicate keys on reduce output

Hi All,

I am working Amazon MR since last 2 weeks.

I created Hadoop Map Reduce Program from release 0.18.3 which Amazon Ec2
supports.

The issue is that map output collector only sends one key , but when I
iterate in reduce method I get duplicate keys.
Although locally it works fine but on EC2 i find duplicate keys in my output
file



Ankit
