Jeff Zhang commented on TEZ-2249:
---------------------------------
[~hitesh] As my understanding, when vertex commit happens it would delete the
temporary folder. But at that time the speculated task attempt may still be
running and using this temporary folder. So the temporary folder may can not be
cleanup. This case should also happen when vertex abort. MR don't have this
issue ?
> Wait for all task attempt finished before moving Task to finished state

> 2 cases:
> * If Task needs to move the SUCCEEDED, then committing may happens while
> there's still task attempt running.
> * If Tasks needs to move to FAILED/KILLED/ERROD, then aborting may happens
> while there's still task attempt running.
