Description

From YARN-2789,

Sigh.

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.

I am inclined to have a separate test-only public util API that keeps compatibility for tests. Rather than opening unwanted APIs up. I'll file a separate ticket for this, we need all YARN apps/frameworks to move to that API instead of these private unstable APIs.

For now, I am okay keeping a private compat for the APIs changed in YARN-2698.
