Soft Limits and Hard Limits in HortonWorks

I am trying to figure out how to configure soft limits and hard limits for the memory subsystem (Cgroups) in Hortonworks. I was successful in configuring it in Cloudera. But, I haven't found anything as such in Horton Works.
Can anyone let me know, is there a way to configure at all, as I couldn't find anything related to this in any of the Hortonworks documentation?
If yes, How?
Thank you.

I looked in many websites and watched many tutorials but they were confusing and didn't help at all.. could you please help me
Thank you
You can use Wireshark for listening for network traffic and capturing the packets. A command-line version - T-shark can output structured XML, which you can store into the database using the programming language / tools of your choice.

Snort Inline with 1 NIC

Is this possible? A group of us have been trying to prepare for a security competition coming up, but we know we will only have 1 NIC. We have tried for hours to research a solution, but we haven't found anything that works. Can anyone point us in the right direction?
Yes, that's possible.
The best way to test playing with Snort is to download the free Linux distro, Security Onion (http://code.google.com/p/security-onion/wiki/Installation). It comes with an easy set-up wizard and has all the tools for Intrusion Detection and Network Security Monitoring.
You can use it to set the server and sensor elements for Snort on the one nic in the VM, eth0 typically. You'll be up and running within 10 minutes of booting the VM.
