Description

Using the following code to do some work-

public class TestMACWithRealInstance {
  public static void main(String args[]) throws IOException, AccumuloException, AccumuloSecurityException, TableExistsException, InterruptedException {
    MiniAccumuloConfig macConfig = new MiniAccumuloConfig(new File("/tmp/mac"), "secret");
    macConfig.setNumTservers(2);
    MiniAccumuloCluster mac = new MiniAccumuloCluster(macConfig);
    mac.start();
    mac.getConnector("root", "secret").tableOperations().create("macCreated");
    mac.stop();
  }
}

It works fine against 1.6.0, but it seems broken against 01da4f4a8b14a125d3a2e29ef98dd044ab9ec75f after calling stop() it just sits in the terminal spewing messages about unable to connect to zookeeper

Issue Links

• breaks: ACCUMULO-3055 calling MiniAccumuloCluster.stop multiple times fails with NPE
• breaks: ACCUMULO-2984 Enable running MAC using an existing instance
• is broken by: ACCUMULO-2764 Stopping MAC before it's processes have fully started causes an indefinite hang
