> Some ideas from [~hossman] in SOLR-14033
> * some dev docs (package level javadocs?) explaining the whole {{org.apache.hadoop}} "shadow" class impls
> * ideally include some hook in {{HdfsTestUtil}} that causes it to fail fast if it can detect that the classloader didn't pick up our modified classes? .. maybe by adding a new {{public static final Object SOLR_HACK_FOR_CLASS_VERIFICATION = new Object}} to each {{org.apache.hadoop.\*\*}} that it could check for via reflection?
