--------------------------------
Summary: Add regression tests for SPARK-8470
Key: SPARK-8489
URL: https://issues.apache.org/jira/browse/SPARK-8489
Project: Spark
Issue Type: Bug
Components: SQL, Tests
Affects Versions: 1.4.0
Reporter: Andrew Or
Assignee: Andrew Or
Priority: Critical
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.
