A very big privilege.

This is a domain, so the only files with this type should be the /proc/pid ones, which don't require associate permissions.

I did my best locking down the ports hadoop uses. Unfortunately the services use high, randomized ports making
tcp_connect_generic_port a must have. Hopefully one day hadoop will settle on static ports. I added hadoop_datanode port 50010 since it is important to lock down that service. I changed the patch based on the rest of the comments.
