Subject Map slots and Reduce slots
Date Sun, 14 Jul 2013 17:44:56 GMT
Does the properties mapred.map.max.tasks=3 and mapred.reduce.max.tasks=4
means that machine has 3 map slots and 4 reduce slots?

Or is there any way i can determine the number of map slots and reduce
slots that i can allocate for a machine?

Let's say on a machine if i have 8GB RAM and dual core machine, how can i
determine that what would be the optimal number of map and reducer slots
for this machine
