清理临时区域错误：Hadoop

我正在hadoop上运行map reduce代码，出现以下错误：

INFO mapreduce.JobSubmitter:清理暂存区域文件：/home/dataflair/hdata/mapred/staging/intern124288574/.staging/job\u local124288574\u 0001 线程“main”ExitCodeException exitCode=1中出现异常：chmod:无法访问“/home/dataflair/hdata/mapred/staging/intern124288574/.staging/job_local124288574_0001”：没有这样的文件或目录

您试图访问的文件不允许您访问权限。要解决这个问题，你必须自己显式地更改文件权限。但它试图访问一个直接位于主目录下的文件，我想这应该是一个用户目录。而且，也没有这样的目录已经存在，如果是这样的话，那么你的应用程序正在查找当前不存在的目录。尝试自己创建一个目录，并为该目录提供适当的权限。有时，这是一个解决办法，但它的搜索目录直接在主目录下。我甚至可以在那里建立一个目录吗？我的意思是在两者之间应该有我的用户名。像home/{usename}/dataflair/…对我来说，将这个属性添加到warn-site.xml中是有效的。。warn.nodemanager.local-dirs/home/{username}/
