我在virtualbox中下载并启动了hdp2.0,然后尝试使用yarclient从java连接

YarnClient client = YarnClient.createYarnClient();  
    client.init(new Configuration());
    client.start();
    client.createApplication();

但遇到以下错误:

1311 [IPC Client (1943692956) connection to /192.168.0.31:8050 from lordorient] DEBUG org.apache.hadoop.ipc.Client.run null – IPC Client (1943692956) connection to /192.168.0.31:8050 from lordorient: starting, having connections 1

有什么问题吗?
我使用的是来自central repo的hadoop库版本2.1.0-snapshot,这是我的yarn-site.xml

连接达到目标。只是查看了服务器日志,似乎是授权问题:

但是所有的文档都对我应该如何配置这些安全性的东西保持沉默。有没有人对hortonworks产品有实际操作经验?

当前版本的hortonworks hdp2.0vm只能使用取自vm本身的libs。以下是需要执行的操作说明:http://fusionworks.md/connecting-to-yarn-on-hortonworks-hdp-2-0/
