----------------------------------------
cc : [~botong]
Mapreduce application for initial containers after restart containers are
assigned without NMToken, ContainerLaunches are failing with invalid token for
containers assigned from secondary subclusters.
> Mapreduce application container start fail after AM restart.

> URL: https://issues.apache.org/jira/browse/YARN-8980
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Bibin A Chundatt
> Priority: Major
>
> UAM to subclusters are always launched with keepContainers.
> On AM restart scenarios , UAM register again with RM . UAM receive running
> containers with NMToken. NMToken received by UAM in
> getPreviousAttemptContainersNMToken is never used by mapreduce application.
> Federation Interceptor should take care of such scenarios too. Merge NMToken
> received at registration to allocate response.
> Container allocation response on same node will have NMToken empty.
