Jason Lowe updated TEZ-3102:
----------------------------
Attachment: TEZ-3102.001.patch
Attaching a patch that does sufficient processing of the kill event for the
task that lost the speculation race to prevent the task state machine from
thinking it still has outstanding attempts.
> Fetch failure of a speculated task causes job hang

> If a task speculates then succeeds, one task will be marked successful and
> the other killed. Then if the task retroactively fails due to fetch failures
> the Tez AM will fail to reschedule another task. This results in a hung job.
