Cannot open channel to 1 at election address

这段时间搭hbase集群，启动hbase的时候，出现了以下异常：

 

2011-05-16 15:07:21,171 - WARN  [WorkerSender Thread:QuorumCnxManager@384] - Cannot open channel to 1 at election address /192.168.0.103:3888

在网上找了相关的资料，说这个异常可以忽略，原因是还有节点没有启动zookeeper，全部启动之后，自然就不会出异常了。
通过日志观察发现，这些异常信息确实都在启动的时候报出的，后面zookeeper就都能连接了，hbase也能正常使用，这也说明这位兄弟的解释的对的。
呵呵，不过看到日志中打印这么多异常，心里却是不太爽啊！所以后期的安排打算看看这部分的程序，希望能规避这样的异常。
