Subject [jira] [Comment Edited] (ACCUMULO-2592) Add new interfaces that better allow extension/implementations of Accumulo clusters

bq. That particular experimental annotation was specifically introduced for the configuration

I wish you had stated that previously when I mentioned it before writing this up then :)

Since you have opinions about this, I assume you also have an interest in how this looks?
Such an API can be placed into the release notes for 1.6.0 for advertisement. What else do
you want to discuss?

Edit: Leveraging Hadoop's InterfaceStability and InterfaceAudience is likely a well suited
approach here if you were to ask me. I'd assume they have a good grasp on things by now (not
to mention the other projects which also leverage the annotations).

> From the conversation on dev@a.a.o, this is ticket encapsulate additions to the minicluster
codebase. These changes decouple the AccumuloMiniCluster implementation from any "programmatically
deployed" Accumulo cluster. 
> It defines an AccumuloConfig and AccumuloCluster, which the existing AccumuloMiniConfig
and AccumuloMiniCluster implement with changing the API. These new interfaces and the factory
to create implementations of them are marked as experimental and reside in their own package
as they are being introduced so late in the 1.6.0 game.
> The existing classes which are in the "public api" are not modified -- the only changes
made were done internally. The internal MiniAccumuloCluster and MiniAccumuloConfig classes
now implement these new interfaces, have appropriate override annotations, and contain a new
{{build}} method on the AccumuloConfiguration implementation to simplify the factory.
