Technical question on Capacity Scheduler.
Hi

I am going through the Capacity Scheduler implementation. There is one
thing i did not understand clearly.
1. Does the o ff-switch task refers to a task in which data has to be
fetched over the network. It means its not node-local ?
2. Does off-switch task  includes only the tasks for which map input has to
be fetched from a node on a different rack across the switch or it also
includes task where data has to be fetched from another node on same rack
on same switch?
