Robert Kanter updated MAPREDUCE-6409:
-------------------------------------
Attachment: MAPREDUCE-6409.002.patch
The new patch renames the enum to {{FAILED_BY_YARN}}. The checkstyle warnings
are all for lines in the state machine transitions, which currently match the
rest of the lines so I don't want to fix those.
> NM restarts could lead to app failures

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.7.0

> Consider the following scenario:
> 1. RM assigns a container on node N to an app A.
> 2. Node N is restarted
> 3. A tries to launch container on node N.
> 3 could lead to an NMNotYetReadyException depending on whether NM N has
> registered with the RM. In MR, this is considered a task attempt failure. A
> few of these could lead to a task/job failure.
