Support for a per-class cluster in ClusterMapReduceTestCase
-----------------------------------------------------------
Key: HADOOP-4902
URL: https://issues.apache.org/jira/browse/HADOOP-4902
Project: Hadoop Core
Issue Type: Improvement
Components: test
Reporter: Tom White
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.
