                一步一步教你怎样给Apache Spark贡献代码
              
          
        
      
        
  
      
    本文将教大家怎样用10个步骤完成给Apache Spark贡献代码这个任务：）
到 Apache Spark 的github 页面内点击 fork 按钮
你的github帐户中会出现 spark 这个项目
本地电脑上， 使用
git clone [你的 spark repository 的 github 地址]
例如：
git clone git@github.com:gchen/spark.git
本地得到一个叫 spark 的文件夹
