While this was a decent effort (it actually made my classpath-related error
almost readable, where previously it was three screens worth of text), there is
still an issue with classpath's lack of simplicity. In partcular, it pulls in
(without any obvious documentation) many different classpaths, some of which
may depend on environment variables. I'm currently (Zeppelin master, HDP 2.2w/
spark tech preview on yarn) getting "bad substitution" errors from
launch_container.sh:27, an issue similar to Ambari-8028
(https://issues.apache.org/jira/browse/AMBARI-8028) and which I suspect is down
to remaining references to ${hdp.version} (and potentially $PWD,
$HADOOP_CONF_DIR), which I'm chasing down now.
I think it might be a good idea to move the classpath over to
zeppelin-site.xml in any case, since over the long term managing the classpath
via shell scripts is going to be painful and not user-friendly. Especially the
CLASSPATH+= makes identifying the issue I encountered very difficult.
