For Hue access to HDFS I'd actually recommend configuring
Hadoop's HTTPFS. I find it a little bit more convenient that
way:

It looks that somehow you're ending up logging in Hue as root (UID 0).
This won't work. You need to create a regular Unix user AND a corresponding
Hue user (just the same user name) to be able to submit jobs.
