上周，我使用用户“root”启动hadoop的dfs&mapreduce并运行嵌入的pig java代码。一切正常。本周，我将使用非root用户charlie执行相同的任务。在更改了几个目录的用户权限设置之后，现在我可以使用用户“charlie”启动hadoop的dfs&mapreduce，并且没有任何错误。但是，当我使用用户“charlie”运行嵌入的pig java代码时，它总是抱怨我在core-stie.xml中设置为/opt/hdfs/tmp/的hadoop.tmp.dir的权限：
java.io.filenotfoundexception:/opt/hdfs/tmp/mapred/local/localrunner/job\u local\u 0001.xml（权限被拒绝）
我已经检查了以下目录的权限，它们看起来都不错：

bash-3.2$ ls -lt /opt/hdfs/tmp
    total 4
    drwxr-xr-x 3 charlie comusers 4096 Apr 16 19:30 mapred
    bash-3.2$ ls -lt /opt/hdfs/tmp/mapred
    total 4
    drwxr-xr-x 2 charlie comusers 4096 Apr 16 19:30 local
    bash-3.2$ ls -lt /opt/hdfs/tmp/mapred/local
    total 0

我需要一些关于我做错了什么的指导。我在谷歌上搜索了那些关键词，但什么也没找到。任何帮助都将不胜感激！
我附上了清管器输出如下。希望这些信息能有所帮助。
