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.
