Vinod K V commented on MAPREDUCE-1116:
--------------------------------------

This will also delay releasing the slot till localization (for the killed task) finishes.

> Even after the task is marked for killing, because TT doesn't explicitly check for the task state at various stages like downloading job jar, job conf and distributed cache files, it continues to localize the task. This is waste of resources and time and in some cases affects other tasks. Particularly it continues to download distributed cache files and aggravates issues like MAPREDUCE-1098.
