我试图在我的学校提供的集群上建立与远程HBase的连接，但它失败了。 我在没有HBase的情况下在我自己的机器上执行如下代码：

这是我的错误＆＃34;：
public class HBaseApp {
public static void main(String[] args) throws IOException, ServiceException {
Configuration conf = HBaseConfiguration.create();
HBaseAdmin admin = null;
String ip = "149.202.86.142";
String port = "2181";
conf.set("hbase.zookeeper.quorum", ip);
conf.set("hbase.zookeeper.property.clientPort", port);
try {
admin = new HBaseAdmin(conf);
boolean bool = admin.tableExists("myTable");
System.out.println("Table exists? " + bool);
} catch (IOException e) {
e.printStackTrace();
}
}
}
等等。
我使用Maven链接依赖项。
我必须确切地说我无法控制服务器的配置。 有谁知道我错过了什么？
