      Description

      Currently, our puppet deployment topology is putting a log of services on the hadoop_head_node. This puts unnecessary resource stress on it. I propose we start deploying a few services onto the gateway node itself.

        I think there's another issue with ZK quorum for HBase, which is configured to be on the head node. Normally though you'd expect to find it on slaves.

        Konstantin Boudnik agreed. Ideally we'd want to run 3 ZK quorum so that our tests deployments are close to what's running in production. Unfortunately, our puppet code is not sophisticated enough to let one easily implement that type of topology.

        That said, I really think that for the type of testing we do – running one ZK on a head node is more than enough.
