\[color=green\]\[size=large\]\[b\]散仙，最近再用Sqoop从Mysql数据库里向Hbase里导入数据，导入成功后，在eclipse上使用Java Hbase API的连接集群，打印所有数据，结果一运行程序，日志显示无法定位登录配置，具体信息如下：\[/b\]\[/size\]\[/color\]

\[b\]\[color=olive\]\[size=large\]其实这个信息，并不是Hbase的异常，而是客户端找不到zookeeper的解析地址，由于Hbase是通过hostname解析IP地址的(DNS)，Zookeeper只会返回Hbase的域名，需要客户端通过DNS或本地hosts文件进行解析。  
解决办法：  
在Linux上，在/etc/hosts文件中添加Hbase Master节点的域名及IP地址映射，  
在Windows上，修改C:\\Windows\\system32\\etc\\hosts文件，添加Hbase Master节点的域名及IP地址映射。  
截图如下：

\[b\]\[color=olive\]\[size=large\]至此，就可以正常使用了，再次启动程序，已经发现没有刚才的问题了\[/size\]\[/color\]\[/b\]
