--------------------------------------------------------------
bq. That's not true, you just don't understand. Running HDFS loads a lot of
those classes. Using the client API's load a lot less of those classes. It's
pretty simple...
Can we put the client classes into a smaller JAR? Is there none available in
Maven? Then we would add the student-first-year MiniDFSCluster into a separate
JAR and run it only with tests. This would not solve the permgen problem, but
would make the Solr WAR smaller. It would also ensure, that no core class
accidently starts hadoop (in extra slow mode, just joking).
Ideally, can we start a separate HDFS cluster (empty) in a parallel JVM next to
all tests and use that one remotely (as it would be in reality - the cluster
would also not run in the same JVM). Means, ant starts an empty HDFS cluster
and all tests use it as data store?
