@Paul Hargis Follow up question. I have a topology that used both hBase and ElasticSearch 2.1. hBase depends on guava 1.3 and ElasticSearch 2.1 depends on guava 1.8. Can I include both versions of guava? I somehow need to tell maven to rewrite the Elastic byte code to refer to the relocated guava 1.8, but to NOT rewrite hBase byte code, so it continues to find guava 1.3. Is this possible? How? ( It seems I could do this by breaking up my project into more pom files and isolating them that way, but that will break the more functional segmentation of my multi-pom project, so maybe there is a more direct way?) ...
