Gregory Chanan updated SOLR-5865:
---------------------------------
Attachment: SOLR-5865addendum.patch
I think the issue is that the System properties are not cleared and can have
effects on later tests. Here's a version that clears them...I was able to run
all the unit tests successfully with this applied. Mind giving this a spin,
Mark?

> Today, the SolrCloud tests are based on the LuceneTestCase class hierarchy,
> which has a couple of issues around support for downstream projects:
> - It's difficult to test SolrCloud support in a downstream project that may
> have its own test framework. For example, some projects have support for
> different storage backends (e.g. Solr/ElasticSearch/HBase) and want tests
> against each of the different backends. This is difficult to do cleanly,
> because the Solr tests require derivation from LuceneTestCase, while the
> other don't
> - The LuceneTestCase class hierarchy is really designed for internal solr
> tests (e.g. it randomizes a lot of parameters to get test coverage, but a
> downstream project probably doesn't care about that). It's also quite
> complicated and dense, much more so than a downstream project would want.
> Given these reasons, it would be nice to provide a simple
> "MiniSolrCloudCluster", similar to how HDFS provides a MiniHdfsCluster or
> HBase provides a MiniHBaseCluster.
