Thanks Neeraj, though I don't understand the following: my storm nimbus is installed and running on a node where zookeeper is running on default port 2181. As I am using the storm topology from the tutorial (and I assume the topology is running from the nimbus node) does that mean the zookeeper address is somewhat hardcoded in the topology? ... I deployed the topology though from a node where zookeeper is not running (if that matters) ... As I am just starting with Storm playing around I might just have a lack of understanding for how things working together, so sorry for that!
you need to tell storm the zookeeper quorum. So go to storm config, search for the property below and specify your zookeeper host if only one or quorum if 1+ (comma separated list of zookeeper servers). Look at the screenshot.
