Hello,I have a small cluster and I am running MapReduce WordCount application
in it.
I want to print some variable values in the console(where you can see the map
and reduce job progress and other job information) for debugging purpose while
running the MapReduce application. What is the easiest way to do that?
Thanks in advance.
