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： 15/07/27 15:18:21 INFO zookeeper.ClientCnxn: Opening socket connection to server 127.0.0.1/127.0.0.1:2181.

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);
