Bikas Saha commented on TEZ-808:
--------------------------------
Fixing IOs vs Fixing processor callback - which one of these would benefit the
case for the stack trace shown above?
I am not sure if the processor was waiting for a tuple from an IO or from
somewhere else? If it was an IO then was it a Tez framework IO? If yes, could
you please open a bug with the logs so that the IO hung issue can be separately
investigated.

> If a task attempt is not making progress then it may cause the job to hang.
> We may want to kill and restart the attempt. With speculation support and
> free resources we may want to run another version in parallel.
