Hitesh Shah commented on TEZ-14:
--------------------------------
Mostly looks ok. The real test will be to run this on some larger clusters and
verify it in practice.
Follow-up jira which should likely be done before a 0.6 release - add counters
to track no. of speculated attempts launched, in how many cases did the
speculated task attempt "win" amongst other things.
> Support for speculation of slow tasks
