> 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
> Fix For: 1.4.1, 1.5.0
>
>
> 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.
