Can you provide the Dataset link which is used to run these examples

@learnhadoop4081

Have few question on this?
1. in code you have set 2 reduce task. Hence will get two reduce result file. Is it possible to merge two output file into one single file after reduce job done.

2.  In Driver class we are specifying map key and value . suppose Map output value is Text and combiner output is some custom class (implemented writable ). so in that case which output value need to pass in setMapValue method
