> See SPARK-8470 for more detail. Basically the Spark Hive code silently overwrites the
context class loader populated in SparkSubmit, resulting in certain classes missing when we
do reflection in `SQLContext#createDataFrame`.
> That issue is already resolved in https://github.com/apache/spark/pull/6891, but we should
add a regression test for the specific manifestation of the bug in SPARK-8470.
