Navis created HIVE-4484:
---------------------------
Summary: Current hive is slower than previous versions
Key: HIVE-4484
URL: https://issues.apache.org/jira/browse/HIVE-4484
Project: Hive
Issue Type: Task
Environment: ubuntu 10.10, 4G, i7-8core
Reporter: Navis
Comparing logs for various patches, I've found query execution become slower
than before. For example, (picked not-changed tests)
{noformat}
ppr_pushdown.q
135~140 sec : 2012-03-27 ~ 2012-07-17
140~160 sec : ~ 2012-11-28
160~220 sec : ~ 2013-03-30
220~250 src : ~ current (HIVE-4392)
join_nulls.q
295~310 sec : 2012-03-27 ~ 2012-07-17
310~330 sec : ~ 2012-11-28
330~370 sec : ~ 2013-03-30
400~460 src : ~ current (HIVE-4392)
{noformat}
This explains much on recent prolonged test time. It might be from changes on
test framework. But still need investigation before adding more functionality
into hive.
