Subject Incresing map reduce tasks will increse the time of the cpu does this seem to be correct
Date Thu, 13 Dec 2012 10:31:38 GMT

I am trying to increase the number of map and reduce tasks for a job and
even for the same data size, I noticed that the total time CPU increases but
I thought it would decrease. MapReduce is known for performance calculation,
but I do not see this when i  do these small tests.

What de you thins about this issue ?
