Jeff Zhang commented on TEZ-2581:
---------------------------------
bq. Did you miss responding to the above comment?
Edit the previous comment, and added it.
bq. Got it. Alternatively, if changing the singleArcTransition to a MultipleArc
also sounds feasible by adding a return state that defaults to fail_in_progress
and is overridden to failed state only in the recovery case. The multiple arc
transition seems more generic and may be used in the future for other things
that want to short circuit the transition IMO.
Will try that.
bq. TEZ-2939? (not sure since there is no description). We can close it if the
cases are already covered.
Forget to mention that I think I still miss one case of system test: Multiple
rounds of recovery (AM crash again and again) Will try to add it in this patch
if possible.
