Subject No. of Map and reduce tasks
Date Thu, 26 May 2011 21:48:20 GMT
How can I tell how the map and reduce tasks were spread accross the
cluster? I looked at the jobtracker web page but can't find that info.

Also, can I specify how many map or reduce tasks I want to be launched?

>From what I understand is that it's based on the number of input files
passed to hadoop. So if I have 4 files there will be 4 Map taks that
will be launced and reducer is dependent on the hashpartitioner.
