[jira] Created: (HIVE-1470) percentile_approx() fails with more
than 1 reducer
percentile_approx() fails with more than 1 reducer
--------------------------------------------------
Key: HIVE-1470
URL: https://issues.apache.org/jira/browse/HIVE-1470
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.6.0
Reporter: Mayank Lahiri
Assignee: Mayank Lahiri
Fix For: 0.7.0
Attachments: HIVE-1470.1.patch
The larger issue is that a UDAF that has variable return types needs two inner Evaluator classes. This patch fixes a NullPointerException bug that is only encountered when partial aggregations are invoked.

[jira] Commented: (HIVE-1470) percentile_approx() fails with more
than 1 reducer
Posted by "John Sichi (JIRA)" <ji...@apache.org>.

John Sichi commented on HIVE-1470:
----------------------------------
How about this..post an updated patch which includes the test case, setting the number of reducers explicitly. It will be ignored for now (so the test coverage won't actually be there yet), but I'll add a note on HIVE-117 that this is a test that needs to start running in minimr mode once HIVE-117 is fixed.

----------------------------------
Oh...if it requires more than one reducer, we'll need minimr mode in order to exercise it, meaning I need to finish HIVE-117.

Mayank Lahiri commented on HIVE-1470:
-------------------------------------
Should I create a dependency on HIVE-117? The only bit that was causing the code to crash has been removed with the split-up of the Evaluator class.
