    Description

      I'm trying to run test suite on a local machine. I never get to the second part because I fail on below test with below exception near every time (and an ipv6 test... will do that next).

      1 -------------------------------------------------------------------------------
      2 Test set: org.apache.hadoop.hbase.zookeeper.TestZooKeeperMainServer
      3 -------------------------------------------------------------------------------
      4 Tests run: 2, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 16.161 s <<< FAILURE! - in org.apache.hadoop.hbase.zookeeper.TestZooKeeperMainServer
      5 testCommandLineWorks(org.apache.hadoop.hbase.zookeeper.TestZooKeeperMainServer) Time elapsed: 15.848 s <<< ERROR!
      6 org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /testCommandLineWorks
      7 at org.apache.hadoop.hbase.zookeeper.TestZooKeeperMainServer.testCommandLineWorks(TestZooKeeperMainServer.java:81)

      Looks like running the command before we are connected causes the above – we pause 15 seconds and then throw the above. If I wait until connected before proceding, stuff seems to work reliably. I don't have access to the watcher on connections since we override the zk main class... so this seems only avenue available at mo (This zk main thing is all a hack around zk main because it had bugs ... but I think we have to keep the hack because folks use different versions of zk. My $workplace defaults to something that is years old, 3.4.5 for instance).
