I'm having a conflict running elasticsearch and neo4j together. Even running ElasticSearch in transport mode requires the Lucene jars, but only the Version class in org.apache.lucene.util.Lucene. It would be nice if elasticsearch could run in transport mode with no Lucene dependencies. Is there any other way around this?

I'm working on an alternative approach to the current ES code, so you can choose between ES clients: (bulk) index only for ingesting (for example push clients), query only (to deny modifications), index and query, or full admin access client. Also I want to implement a Java TransportClient API wrapper around Netty HTTP/Websocket connections to get rid of the JVM compatibility and Zen discovery ES version issues (comparable to Perl/Python/Ruby client via HTTP). For query clients, the Lucene query jars are always required. In my experiments some time ago on 0.20 codebase I created a simple ES Java ingest client with 2 MB size only. Sorry, there is no quick result available yet. My approach requires thorough modularization of the current ES codebase, and takes some time, I do it in my spare time.

I would be happy if ES shaded the Lucene jars, they do it for the netty and other libraries, I'm not sure why they don't do it for Lucene unless the Lucene API leaks out of the ES one (that is, a client of ES needs to refer to Lucene code as part of interacting with it).
