> Some work has been done to make sure the tasktrackers kill process trees of tasks when they finish (either successfully, or with failures or when they are killed). Related JIRAs are HADOOP-2721, HADOOP-5488 and HADOOP-5420. But when TTs are restarted, we do not handle killing of process trees - though tasks will themselves die on re-establishing contact with the TT.
