---------------------------------------
Summary: Huge performance gap when processing ORC files created by
Spark
Key: HIVE-20200
URL: https://issues.apache.org/jira/browse/HIVE-20200
Project: Hive
Issue Type: Bug
Components: Hive, ORC
Affects Versions: 2.1.0
Reporter: Vinoth Sathappan
Seeing a huge performance difference while running a simple filter query on ORC
files created by Spark. I'm seeing better performance if the files are written
by Hive i.e. after doing a "create table x as select * from y".
