我正试图在一个没有管理权限的集群上使用MRJob运行python脚本，我在下面粘贴了错误。我认为正在发生的情况是，作业正在尝试将中间文件写入默认的/tmp。。。。dir，由于这是一个受保护的目录，我没有写入权限，所以作业收到一个错误并退出。我想知道如何将这个tmp输出目录位置更改为本地文件系统中的某个位置。例如：/home/myusername/some_path_in_my_local_filesystem_on_the_cluster，基本上我想知道我必须传递哪些附加参数才能将中间输出位置从/tmp/更改为。。。去当地某个我有写作许可的地方。
我调用我的脚本为：
python myscript.py input.txt -r hadoop > output.txt
错误：

您是将mrjob作为"本地"作业运行，还是尝试在Hadoop集群上运行它？
如果您实际尝试在Hadoop上使用它，您可以使用--base-tmp-dir标志：来控制"scratch"HDFS位置（mrjob将在其中存储中间文件）
python mr.py -r hadoop -o hdfs:///user/you/output_dir --base-tmp-dir hdfs:///user/you/tmp hdfs:///user/you/data.txt
