> build spark without hive
It's still possible to build (as in package) a Spark distribution without
Hive. This code already uses reflection, and the new dependencies should be
test-scope only (aside from any issues that still need to be solved).
So you need Hive to run the tests, but you don't need Hive at runtime.
