> I see that spill files are not deleted right after merge completes. We
> should do that as it takes up a lot of space and we can't afford that wastage
> when Tez takes up a lot of shuffle space with complex DAGs. [~jlowe] told me
> they are only cleaned up after application completes as they are written in
> app directory and not container directory. That also has to be done so that
> they are cleaned up by node manager during task failures or container crashes.
