----------------------------------------
Hi Scott,
Our product cluster met a similar problem about job setup-task. We let TT
don't ask for new task when report a failed job setup/cleanup task in heartbeat
to fix this issue. I'll attach our patch based on 0.19.1.
> Task-cleanup task should not be scheduled on the node that the task just
> failed
