    > MiniAccumuloConfig is leaked via a public constructor and the getConfig method on
MiniAccumuloCluster
    
    Yup, that's by design.
    
    > If MiniAccumuloConfig doesn't have a setter for the existing zookeepers, then it
can't be used by an integration test or in general.
    
    Right, it would need to be used via `MiniAccumuloConfigImpl` and `MiniAccumuloClusterImpl`.
We already have many methods hidden on the impl that are not exposed in via the non-impl variants.
Nearly all of our ITs in Accumulo use the impl variants already IIRC.

> A test harness may have already started ZooKeeper for other testing. MiniAccumuloCluster
could use that same ZooKepeer instance, instead of creating its own, but it is currently not
possible given what MAC does now.
