The use case here is that I want to build one common spark that is used
across many different clusters. Those clusters may not have Hive running yet,
or perhaps I just don't want to have to specify hive-site.xml and include
hcatalog, etc. If I'm not using Hive then I don't need spark-shell to load it
for me. Perhaps I'm trying to use Spark and they take Hive down to do
maintenance, now I can't run Spark or I get error messages out.
