今天启动hbase的时候遇到一个问题， 错误如下：

1.在 hbase-localhost-zookeeper-chaobin.log

2.在 hbase-localhost-master-chaobin.out

3.在 hbase-localhost-regionserver-chaobin.log

从源代码中可以看到，throw 中的waitForServerDown方法会MiniZooKeeperCluster抛出异常。这是因为为指定机器上的 zookeeper 服务器分配的端口被其他应用程序使用，或者它根本无法承载流。尝试将端口更改为其他端口，或检查在该端口上运行的应用程序。

如果您使用的是 linux，请输入netstat -tulp|grep port-no一个替换 zookeeper 端口的终端，以查看它是否被其他程序使用。
