say I have a 2 mapper classes, The key-Value output of one is in the form key : Text (Name) and value :Text ("Company name", "address"). and the output of the other mapper class is in the form key:IntWritable (Increment) and Value: IntWritable (1000,2345,6745)
I should have 2 reducer classes, because the input key-value from mapper classes are different.
How do i make the reducer understand to consolidate the output of which mapper class ?
