------------------------------------

             Summary: Decouple MiniAccumuloCluster from integration test base class
                 Key: ACCUMULO-3167
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3167
             Project: Accumulo
          Issue Type: Improvement
          Components: mini, test
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.6.1, 1.7.0


(apologies if I already had a ticket for this somewhere, I couldn't find it)

Our integration tests are very nice and automated at the moment because we can use MiniAccumuloCluster
to "provision" an Accumulo instance (or used a shared instance), and run a test against it.
For the most part, this works well and provides an accurate test harness.

Thus, to run integration tests, you need a sufficiently beefy machine since the same host
will be running all of Accumulo as well as performing any client work. When resources are
available to use, it would be nice to leverage them -- whether these are yarn, mesos, a vanila
installation, etc.

In addition to the additional computational power from using extra hardware, it also encourages
us to use the public API as much as possible instead of relying on "hidden" impl methods in
MiniAccumuloCluster.

I propose making changes to the IT test base (AbstractMacIT, SimpleMacIT, ConfigurableMacIT)
to add an extra step between them an test classes to allow "injection" of a more generic Accumulo
"cluster" that is not associated with MAC.
