我试图连接到远程HDFS群集。我已阅读了一些文档并开始使用，但没有找到最佳解决方案。 情况：我在xxx-something.com上有HDFS。我可以通过SSH连接到它，一切正常。Java/Scala远程HDFS使用情况
但是我试图做的，从它获取文件到我的本地机器。
我做了什么：
我创建核心的site.xml在我的conf文件夹（我创建游戏应用！）。在那里，我已经将fs.default.name配置更改为hdfs：//xxx-something.com：8020（不确定端口）。 然后我试图推出一个简单的测试：
val conf = new Configuration()
conf.addResource(new Path("conf/core-site.xml"))
val fs = FileSystem.get(conf)
val status = fs.listStatus(new Path("/data/"))
而且我得到错误：
13:56:09.012 [specs2.DefaultExecutionStrategy1] WARN org.apache.hadoop.conf.Configuration - conf/core-site.xml:a attempt to override final parameter: fs.trash.interval; Ignoring.
13:56:09.012 [specs2.DefaultExecutionStrategy1] WARN org.apache.hadoop.conf.Configuration - conf/core-site.xml:a attempt to override final parameter: hadoop.tmp.dir; Ignoring.

提前感谢！
更新： 可能是错误的港口。现在我将它设置为22，我仍然得到同样的错误，但经过3次它说：
14:01:01.877 [specs2.DefaultExecutionStrategy1] DEBUG org.apache.hadoop.ipc.Client - Connecting to xxx-something.com/someIp:22

而且算账：

是什么意思？
