Resolution: Cannot Reproduce

Internal app ID application_1429683757595_0912, LLAP application_1429683757595_0911. If someone without access wants to investigate I'll get the logs.
I've ran into this only once. Feel free to close as not repro, I'll reopen if I see again I want to make sure some debug info is preserved just in case.
Running Q1 - Map 1 w/1000 tasks (in this particular case), followed by Reducer 2 and Reducer 3, 1 task each, IIRC 3 is uber.
Fetch failed with I'd assume some random disturbance in the force:
AM registered this as Map 1 task failure
Eventually Map 1 completed
Then AM logged this (not sure if it's relevant)
And nothing happened for 4+ minutes until I killed the job.
Reducer 2 had a running attempt:
It looks like it actually completed on LLAP
But AM never received the completion?
