I'm getting that exception when starting a topology with either 0.9.2-incubating-SNAPSHOT I built locally, or 0.9.1-incubating from Central.
The topology is in Clojure. The project.clj dependency is [org.apache.storm/storm-core "0.9.2-incubating-SNAPSHOT"], and I'm using Clojure 1.5.1. >From poking around, it looks like ILookupHost was removed in Clojure 1.2 or 1.3. When using Storm 0.9.0.1, this doesn't happen. My motivation for going to 0.9.2-* is the Kryo issue with Storm/Titan ( https://issues.apache.org/jira/browse/STORM-263). Thanks, Derek
