Based on a quick look through the policy, it looks like the only dir they create in /tmp is this hsperfdata dir.

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. Signed-off-by: Paul Nuzzi <pjnuzzi@tycho.ncsc.mil>
