Hey there, I've updated the Ansible install/configure scripts for Hadoop, right now the repo points to CDH4 but you can change that easily enough.
It needs some cleanup over the next few days, but it should help anyone who's had to do a lot of workarounds to get the 12.04 scripts to work. https://github.com/LusciousPear/PalominoClusterTool -B -- Bradford Stephens, CEO and Founder, Drawn to Scale http://drawntoscale.com (530) 763-DATA http://www.drawntoscale.com -- Spire: Real-Time Big Data
