How to specify the permissions of the directories that are generated by a Hadoop MapReduce job?

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/directory to 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 the dfs.umask value, which will govern the permissions directories are created with.

See http://hadoop.apache.org/docs/r0.20.2/hdfs_permissions_guide.html
