> NM restarts could lead to app failures

> Key: MAPREDUCE-6409
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6409
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.7.0
> Reporter: Karthik Kambatla
> Assignee: Robert Kanter
> Priority: Critical
> Attachments: MAPREDUCE-6409.001.patch, MAPREDUCE-6409.002.patch
>
>
> 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.
