>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: docs, documentation
>            Reporter: Charan Hebri
>            Assignee: Gour Saha
>            Priority: Major
>         Attachments: YARN-8226.01.patch
> The anti-affinity section in the YARN services doc says,
> {noformat}
> Note, that the 3 containers will come up on 3 different nodes. If there are less than
3 NMs running in the cluster, then all 3 container requests will not be fulfilled and the
service will be in non-STABLE state.{noformat}
> Based on the description the expected behavior for the case of number of NMs less than
the number of containers requested isn't very obvious. Opening issue to improve the comment.
