URL: https://issues.apache.org/jira/browse/HIVE-14919
Project: Hive
Issue Type: Improvement
Reporter: Ferdinand Xu
Assignee: Ferdinand Xu
Attachments: benchmark.xlsx
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.
