Rajesh Balamohan commented on TEZ-3317:
---------------------------------------
No harm in porting to 0.7, but [~jeagles] would have more info on whether this
needs to be backported to 0.7.
> Speculative execution starts too early due to 0 progress

> Don't know at this point if this is a tez or a PigProcessor issue. There is
> some setProgress chain that is keeping task progress from being correctly
> reported. Task status is always zero, so as soon as the first task finishes,
> tasks up to the speculation limit are always launched.
