Some status on this:
* One of the four hadoop precommit jobs (HADOOP) is now running from
the YETUS-83 branch. It’s very hacky Jenkins-wise but working.
* Thus far, I've hit ~10 bugs in the process, with the only
particularly fatal one being that plugins aren’t being properly loaded in
docker mode. So docker mode wasn’t turned on. :( The rest were almost all
visual, errors going to screen, etc, type bugs that don’t appear to impact the
core functionality.
* Multiple JDKs and multiple maven repo support are turned on, however,
and appear to be functioning as expected.
