Description

  public static void tearDownAfterClass() throws Exception {
    htable2.close();
    htable1.close();
    admin.close();
    utility2.shutdownMiniCluster();
    utility1.shutdownMiniCluster();
  }

If the setUpBeforeClass() fail, some members will be NULL. We need to ensures all resources are closed at the end of tests.
