HBase已经常启动，在shell里也可以正常操作，但在eclipse中java操作HBase时，报如下错误：

解决方法：

在代码中，Configuration里设置hbase.zookeeper.quorum，指定sdw1、sdw2，如果hosts中没有配置sdw1、sdw2解析ip，要直接将sdw1和sdw2换成对应ip，如：

Configuration conf=HBaseConfiguration.create();
    conf.set("hbase.zookeeper.quorum", "sdw1,sdw2");
    HBaseAdmin admin=new HBaseAdmin(conf);

Configuration conf=HBaseConfiguration.create();
    conf.set("hbase.zookeeper.quorum", "192.168.10.201,192.168.10.202");
    HBaseAdmin admin=new HBaseAdmin(conf);
