> In HIVE-14029, we have updated Spark dependency to 2.0.0. We use Intel
> BigBench[1] to run benchmark over 10 GB data set comparing with Spark 1.6. We
> can see quite some performance degradations for all the queries of BigBench.
> For detailed information, please see the attached files. This JIRA is the
> umbrella ticket addressing those performance issues.
