> When the test runs, I see this at the start of the output:
> {code}
> 2011-09-21 04:56:35,282 INFO  [main] zookeeper.MiniZooKeeperCluster(122): Failed binding
ZK Server to client port: 21818
> 2011-09-21 04:56:35,344 INFO  [main] zookeeper.MiniZooKeeperCluster(136): Started MiniZK
Server on client port: 21819
> {code}
> So, I think what is going on is that the test is connecting to the wrong zk ensemble
because it does this on setup:
> {code}
>   @BeforeClass
>   public static void setUpBeforeClass() throws Exception {
>     conf1 = HBaseConfiguration.create();
>     conf1.set(HConstants.ZOOKEEPER_ZNODE_PARENT, "/1");
>     // smaller block size and capacity to trigger more operations
>     // and test them
>     conf1.setInt("hbase.regionserver.hlog.blocksize", 1024*20);
>     conf1.setInt("replication.source.size.capacity", 1024);
>     conf1.setLong("replication.source.sleepforretries", 100);
>     conf1.setInt("hbase.regionserver.maxlogs", 10);
>     conf1.setLong("hbase.master.logcleaner.ttl", 10);
>     conf1.setBoolean(HConstants.REPLICATION_ENABLE_KEY, true);
>     conf1.setBoolean("dfs.support.append", true);
>     conf1.setLong(HConstants.THREAD_WAKE_FREQUENCY, 100);
>     utility1 = new HBaseTestingUtility(conf1);
>     utility1.startMiniZKCluster();
> ....
> {code}
> and we refer to conf1 subsequently rather than to HTU.getConfiguration.
