Bikas Saha commented on MAPREDUCE-3921:
---------------------------------------
Attaching a patch that builds on MAPREDUCE-3353
1) RMContainerAllocator receives node updates along with allocated containers
2) It sends KILL event to map task attempts running on unusable nodes
3) It sends a JobUpdatedNode event to JobImpl
4) JobImpl maintains a mapping of nodes to successful task attempts that have
run on them
5) On receiving updated nodes JobImpl sends KILL event to map task attempts
from 4)
6) Successful task completions retro actively get to the KILLED state if their
successful task attempt is the same as the task attempt in 5). They reschedule
another attempt.
> MR AM should act on the nodes liveliness information when nodes go
> up/down/unhealthy
