我是用JAVA的 hbase客户端调用的（我在本机运行Windows7 hbase在虚拟机里Centos 7）！启动后，ZooKeeper活得sessionId 但就卡在那里了！很久才爆出错误

2018-11-22 11:16:59.132 ERROR 7312 --- [           main] o.a.hadoop.hbase.client.AsyncProcess     : Failed to get region location 

java.net.ConnectException: Connection refused: no further information

解决方法！

一，确定ZooKeeper连接成功

Session establishment complete on server localhost.master/192.168.11.91:2181, sessionid = 0x10000027ab8000c,

我发现我的代码中！发现了这句！说明ZooKeeper连接成功

二，hbase需要绑定本地与虚拟机的IP地址

netstat -anp | grep 16000

确定所对应的是不是虚拟机地址！如果对应的是127.0.0.1是错误的！
