When I run a Hadoop MapReduce job, all the directories that were generated use ‘rwxr_xr_x’ as the permissions. I would like to change them to ‘rwxrwxrwx’, how to do that?

You can use
hadoop fs -chmod 777 your/directoryto change it after the fact. Or create the directories before you run the job, and set their permissions accordingly. You might also be able to set thedfs.umaskvalue, which will govern the permissions directories are created with.See http://hadoop.apache.org/docs/r0.20.2/hdfs_permissions_guide.html
