这段时间搭了一个7台机器的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。
