             Summary: Document SimpleMacIT
                 Key: ACCUMULO-1996
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1996
             Project: Accumulo
          Issue Type: Task
            Reporter: Christopher Tubbs
            Assignee: Christopher Tubbs
             Fix For: 1.6.0


I did some work under ACCUMULO-1599 to split up the existing integration tests that use MiniAccumuloCluster
into two separate groups for testing: those integration tests that require custom configuration
and need intimate knowledge and control of MiniAccumuloCluster, and those that don't.

Those that do, were configured to use ConfigurableMacIT, and those that don't were configured
to use SimpleMacIT.

The intention was that any test that did not need to control MiniAccumuloCluster itself, and
only used the regular Accumulo API for executing its tests, could use a shared instance, represented
by SimpleMacIT. Ideally, we would start this shared instance during the pre-integration-test
phase of the build lifecycle, and leave it running until the post-integration-test. If this
instance was not already running, a JVM-local one could be instantiated for the test to run
(eg. inside Eclipse).

An additional benefit is that we could easily transition these tests, through a single, centralized
configuration option, to run against a full instance (not MiniAccumuloCluster).

However, something changed, and some commits against ACCUMULO-1009 reintroduced some of the
complexity and exposed too much through SimpleMacIT.

We need to document the intention and clean up this class to be simple again (with no knowledge
of MiniAccumuloCluster underneath).
