Subject Prune out data to a specific reduce task
Date Wed, 11 Mar 2015 10:28:53 GMT

I have this job that has 3 map tasks and 2 reduce tasks. But, I want to 
excludes data that will go to the reduce task 2. This means that, only 
reducer 1 will produce data, and the other one will be empty, or even it 
doesn't execute.

How can I do this in MapReduce?
