io.sort.mb and io.sort.factor

Hi,
I want to know that io.sort.mb and io.sort.factor are properties that set
for the whole cluster, or can be set differently per node?

Best regards!

Both of those properties are job-specifiable.

I have not tried this, but they should be settable at tasktracker conf
levels as finals (since the localized jobconf prepared for the task
still loads defaults [and thus the final policies too?]).

I mean if I have cluster consists of 1 master node and 3 slave nodes, can
these 3 slave nodes have different io.sort.mb and io.sort.factor?
