Hi. I am trying to embed both ElasticSearch and Jackrabbit inside one WebApp. Since ElasticSearch and Jackrabbit uses different lucene versions we have a problem. I see that ElasticSearch are embedding almost all depdencies by rewriting package names. But, lucene is not embedded in this way. Is it a good reason why it is not? BR, Sten Roger Sandvik ---

Mainly because when using the TransportClient, there is no need for the Lucene jars.

Thanks. But when I remove the jar dependencies of lucene jars, I get a CLF exception. It seems that some lucene classes are not bundled when starting a local node (with storage). In NodeEnvironment there are dependencies to both org.apache.lucene.store.Lock and org.apache.lucene.store.NativeFSLockFactory. Is this on purpose?

Maybe its because you started a NodeClient and not a TransportClient? NodeClient requires Lucene jars.
