I am poking around and randomly commented out the run() call as shown below.

  public static void main(String[] args) throws Exception {
    File tmpDir = new File(FileUtils.getTempDirectory(), "macc-" +
UUID.randomUUID().toString());

    try {
      MiniAccumuloCluster la = new MiniAccumuloCluster(tmpDir, "pass1234");
      la.start();

      System.out.println("\n   ---- Running Mapred Against Accumulo\n");

      //run(la.getInstanceName(), la.getZooKeepers(), "pass1234", args);

      System.out.println("\n   ---- Ran Mapred Against Accumulo\n");

      la.stop();
    } finally {
      FileUtils.deleteQuietly(tmpDir);
    }
  }

With this change, I get the following exception which I did not
expect. Shouldn't the above code run cleanly?
