After spending some time reviewing the versions and availability of Tomcat for the platforms we have to support I'm leaning towards a solution of making tomcat be part of the Bigtop distribution itself. That will help us get around a sad state of affairs on platforms like CentOS 5 (where only Tomcat 5 is available, and Oozie/HTTPFS need at least 6) and also give a greater control over the versioning of Tomcat in general (we can keep it uniform across all the distros).
