Matt McCline commented on HIVE-18744: ------------------------------------- The *last* row of a batch presented to VectorGroupByOperator (which calls VectorHashKeyWrapperBatch.evaluate) has these row values: [2051-09-16 08:48:38.0, 21117 = date 2027-10-26, ] Somehow that one last timestamp value 2051-09-16 08:48:38.0 gets repeated in a bunch of VectorHashKeyWrappers and should not be. Seems like a classic case of a scratch object getting overwritten. But which one??? > Vectorization: VectorHashKeyWrapperBatch doesn't check repeated NULLs > correctly > ------------------------------------------------------------------------------- > > Key: HIVE-18744 > URL: https://issues.apache.org/jira/browse/HIVE-18744 > Project: Hive > Issue Type: Bug > Components: Hive > Reporter: Matt McCline > Assignee: Matt McCline > Priority: Critical > Attachments: HIVE-18744.01.patch > > > Logic for checking selectedInUse isRepeating case for NULL is broken. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
