Robert Muir commented on SOLR-5022:
-----------------------------------

The tests add a variety of other dependencies and test jars and actually start
up hdfs.

But these account for ~2000 classes whereas the ones in solr.war account for
~3000 classes.
I mean this explains why we see the issue, from a test environment this hadoop
stuff nearly doubled the number of classes. But the "client code" stuff is
heavy too (its still 3000 additional classes).
Really if hadoop integration+tests were in a contrib module, we probably
wouldnt even see the problem, or we could contain it, because its tests would
run isolated in their own jvm(s). Maybe we should do that?
