Gopal V commented on TEZ-1141:
------------------------------
LGTM, I found that this doesn't track NM blacklisting, but that is a completely
different problem.
I've updated patch on HIVE-7838 to use this and it is useful, to narrow down
query failures (particularly reducer OOMs happening).
> DAGStatus.Progress should include number of failed attempts

> Currently its impossible to know whether a job is seeing a lot of issues and
> failures because we only report running tasks. Eventually the job fails but
> before that we have no indication that a bunch of task failures have been
> happening.
