Till lately I've been using 0.20.2 and everything was ok. Now I'm using the latest trunc 0.22.0-SNAPSHOT
and getting the following thrown:

Exception in thread "main" java.io.IOException: The ownership/permissions on the staging directory
s3://my-s3-bucket/mnt/hadoop.tmp.dir/mapred/staging/root/.staging is not as expected. It is
owned by  and permissions are rwxrwxrwx. The directory must be owned by the submitter root
or by root and permissions must be rwx------

(The "it is owned by ... and permissions " is not a mistake, seems like the empty string is
printed there)
