Jason Lowe updated TEZ-808:
---------------------------
Attachment: TEZ-808.branch-0.7.patch
Would it be possible to backport this to branch-0.7? We're going to be on 0.7
for a while, and we'd like this fix (along with TEZ-2918) to be able to catch
hung tasks in production and automatically recover.
Attaching a version of the patch for branch-0.7. It came over fairly cleanly.

> We may want to kill and restart the attempt. With speculation support and
> free resources we may want to run another version in parallel.
