1.官网下载最新稳定版，https://www.h2o.ai/download/ ，如果点击下载无反应，请使用ie浏览器

2.解压h2o-3.18.0.10.zip到目录h2o-3.18.0.10

3.执行命令

cd h2o-3.18.0.10
java -jar h2o.jar -name clusterName

选项参考http://docs.h2o.ai/h2o/latest-stable/h2o-docs/starting-h2o.html#h2o-options

4.找另一台机器或者重新打开一个shell命令窗口，再次输入命令

java -jar h2o.jar -name clusterName

会自动根据-name选项查找存在的集群

  页面下方会显示出导入数据的界面，在search文本框上输入服务器上文件的路径，点击右侧的搜索按钮，页面会列出所有查到到的文件。然后点击Add all,没问题后点击import按钮

6.2 导入本地客户端数据

   如果服务器上不存在要分析的文件，你可以选择上传自己的文件

 6.3 解析导入的数据

  如果你页面刷新了或者页面数据太乱了，你可以在getFrames里找到你刚才导入的数据集

找到我们刚才导入的数据集，点击parse按钮，

 

你可以自己输入列名，选择数据类型及其他修改，最后点击parse完成数据集的格式处理

 

点击上图中的view按钮，会显示下图，然后点击下图中的view data,会进行数据预览

  数据预览查看：

  parse完数据之后，你会发现数据集的扩展名已经由我们的.csv转为.hex，刷新一下页面，点击getFrames
