Subject Only running hadoop Map tasks
Date Tue, 05 Jan 2010 17:13:15 GMT

1 - I would like to see what is output that the Maps is doing on my
example. Is it possible to put hadoop only running Map tasks,
excluding the Reduce tasks?

2 - The output of the Maps is written into a temporary file?

3 - How the output of the maps is passed to the reduce tasks? Is using
a socket or reading a file in the disk?
