Description
Even though this is a private API, it will be used by downstream projects for testing. It'll be useful for this to be re-instated, maybe with a deprecated annotation, so that older versions of downstream projects can build against Hadoop 2.6.
create() being private is a problem for multiple other classes - ContainerId, AppId etc, Container, NodeId ... Most classes on the client facing YARN APIs are likely to be required for testing in downstream projects.
