Quick Install failing in Interrogating node

Question asked by bhuffman on May 15, 2014
Latest reply on Aug 18, 2015 by wochanda
I've spent some time trying to use the quick installer to work with M3.  I'm just doing a proof of concept right now with 4 nodes.  I am using 1 control node and all 4 nodes as data nodes.

As far as I can tell, I've met the pre-requisites.  I'm running RHEL 6.2, python 2.6 and I have the EPEL repository installed and enabled.

Here's what happens:

    [bhuffman@tds5 var]$ sudo /opt/mapr-installer/bin/install -s new
