Description

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.
