ElasticSearch Dependencies

Elastic Stack Elasticsearch

Hi,

ElasticSearch dependencies (when you use it on the JVM) have been reduced
to just lucene. Some jars are not longer needed (jgroups for example) and
some are jarjar'ed. Its in master, and snapshots have been updated.

cheers,

Great, very useful for embedding Elasticsearch in your own project, or
just using client APIs.

Hi,
I have been using transport client of release 0.5.1 for some time to connect
to Elasticsearch nodes. (I could not use node client because I have old
lucene jars in my classpath) When I try to move to the 0.6.0 version, I
realized that some transport client api has a dependency to the lucene jars.
Is this still the case, or does the client really need these dependencies ?

Thanks in advance,

I actually have not tried to create the TransportClient to work without
Lucene classes (basically meaning that any API elasticsearch provides should
be without Lucene classes). Which APIs have you seen that have Lucene
dependencies?

From the meaning of the name "TransportClient", it seems to me that the
client is not related with lucene interface. It gets exception during the
discovery of the other nodes. Here is the trace:

It might be what you derived from it, but I did not try and abstract the
Transport Client from Lucene. Its problematic to try and maintain this, btw,
since it was not designed to be so ...

Hey,

I just pushed a possible fix for this, so Lucene will not be used in the
TransportClient. The problem is that I can't verify this easily in tests,
since its in the same module. If you can test it, it would be great.

That's great, I'll test it ASAP. Thanks
