> ClusterMapReduceTestCase currently creates a new mini cluster for each test 
> case. For many tests this is unnecessary overhead as the test cases could run 
> against the same cluster, one after another, without risking correctness. As 
> a part of this issue we should change tests that subclass 
> ClusterMapReduceTestCase to use a per-test cluster where appropriate.
