zk的KeeperErrorCode = ConnectionLoss错误

额，这东西都快把人搞崩溃了，各类排查各类正常。

最后居然是由于我在客户端未链接上zkserver的时候就进行了create操做形成的错误。

噗， 

Exception in thread "main" org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /servers/server at org.apache.zookeeper.KeeperException.create(KeeperException.java:99) at org.apache.zookeeper.KeeperException.create(KeeperException.java:51) at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:778) at com.example.test.zk.DistributeServer.registerServer(DistributeServer.java:44) at com.example.test.zk.DistributeServer.main(DistributeServer.java:66)

上面这样的错误，在我随便加了一个sleep操做，以后就正常了。

以下：

// Thread.sleep(10000);
        String create = zk.create(parentNode + "/server", hostname.getBytes(), ZooDefs.Ids.OPEN_ACL_UNSAFE, CreateMode.EPHEMERAL_SEQUENTIAL); System.out.println(hostname + "is online.." + create);

 

哎， 贼耽误工夫。
