HttpClient version
I am trying to use Solr inside of another framework (Storm) that provides a
version of HttpClient (4.1.x) that is incompatible with the latest version
that SolrJ requires (4.3.x). Is there a way to use the older version of
HttpClient with SolrJ? Are there any issues with using an earlier SolrJ
(4.0.0) that used HttpClient 4.1.x with 4.3 of the server? I'm really just
looking for options for running Solr in Storm, so any thoughts would be
greatly appreciated.

We've run into this problem when deploying index jobs that run in Elastic
Mapreduce. We've gotten by with an older version of SolrJ, but some of the
fixes and enhancements with SolrCloud that came out in the 4.x series
aren't available if you go back to an earlier version.
In particular, we're running 4.2.1 and we don't have the ability to call
updateAliases on the ZkStateReader to get around this bug:
https://issues.apache.org/jira/browse/SOLR-4664
We've managed to get by so far, however.

An older SolrJ will probably work fine. SolrJ is pretty stable,
overall. If you're using SolrCloud, you'll probably want to use a later
version just to be sure everything works right.
One thing that I would try first is removing jars from Storm that
conflict with SolrJ and provide the upgraded versions in a common lib
directory in your classpath. There's a reasonable chance that Storm
will work just fine with the newer jars.
For my own SolrJ app, I download the newest versions of the jars instead
of using the older versions included with SolrJ.
