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. -- This message is automatically generated by JIRA.
