There is no reason that you can't mark the offending API methods as deprecated in a 1.8.x release, then immediately branch off of that to create a 2.0 and remove the method. Alternatively, we could decide to forego the semver rules for a specific release and make sure to point it out in the release notes.

Also, just to be clear for everyone else: This means that we have *no roadmap* at all for Hadoop 3 support because Accumulo 2.0 is in a state of languish. This is a severe enough problem to me that I would consider breaking API compatibility and fixing the API leak in 1.7/1.8. I'm curious what people other than Christopher think (assuming from his comments/JIRA work that he disagrees with me).
