Hi All, I'm trying to install a hadoop distro via Ambari 1.7 on ~300 nodes. When it comes time to install all of the services, things get weird (for lack of a better term). I've noticed the UI will kind of give up, but if I pdsh out to the clusters, many are still running yum commands. I'm thinking this has to do with the yum repo I set up being on only node, and http kind of topping out. Are there any recommendations regarding setting up the yum repo based on the size of the cluster?
I've also noticed issues with service installations being flagged as "warnings" (their status is orange), but there's no corresponding error in the output from the target host. There is stdout output, but it's something that seems fine such as "Writing file [...] because contents don't match", and then it ends there. Is there a good set of heuristics to figure out what caused the status of the install to be orange? Thanks, Bill
