What do you mean by heterogeneous environment? Do you mean servers
with different number of cores?

One set of the parameters in Hadoop determines the number of map and
reduce slots for each TaskTracker. In a heterogeneous environment,
presumably you would want to have more slots on servers with more
cores compared to servers with fewer cores.
