2018-02-14 Thread Helder Reia
Thank you for your help!
I will want to develop an intrusion detection system with some cluster and
classify algorithms and I was thinking of usong Metron as framework!
How would you recommend doing it?

To be honest, rather than messing about with grub for this, I would follow the 
alternative route outlines in the wiki page.

To be even more honest, I wouldn’t use that method from the wiki and would 
probably go with something like the full dev VM platform if you’re looking to 
do development work. If you’re looking for production scale, a proper mpack 
based install on an existing Ambari managed cluster (see elsewhere for docs on 
how to set one of these up with a hadoop distribution) is probably better.
