Ashwin Ramesh updated TEZ-3810:
-------------------------------
Description:
A task attempt counter that tracks how much time was spent waiting for inputs
in the shuffle phase. We can use this to quickly identify jobs that are wasting
a lot of time on the grid with idle reducer tasks instead of shuffling/merging.
