Subject [jira] [Commented] (HIVE-5583) Implement support for IN (list-of-constants) filter in vectorized mode
Date Wed, 06 Nov 2013 22:14:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13815362#comment-13815362
] 

Eric Hanson commented on HIVE-5583:
-----------------------------------

You're right. However, the Vectorizer class already refuses to vectorize any query that contains
NULL as a literal. So the code works correctly by dropping back to row-at-a-time mode. I'll
edit the code to remove the misleading comment and unnecessary null handling.
