我试图从服务器运行一个简单的火花到s3应用程序,但我一直得到以下错误,因为服务器安装了hadoop 2.7.3,看起来它不包括GlobalStorageStatistics类.http://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/api/org/apache/hadoop/fs/GlobalStorageStatistics.html.我在我的pom中定义了hadoop 2.8.x .xml文件但尝试通过在本地运行来测试它.
如果我必须使用hadoop 2.7.3,我该如何让它忽略搜索或包含该类的解决方法选项？
