Subject [jira] [Commented] (HIVE-19353) Vectorization: ConstantVectorExpression --> RuntimeException: Unexpected column vector type LIST
Date Sun, 29 Apr 2018 21:46:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-19353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16458212#comment-16458212
] 

Matt McCline commented on HIVE-19353:
-------------------------------------

[~vgarg] thanks – I moved vector_list_constant.q to minillaplocal.query.files section
in patch #2 and deleted the TestCliDriver output file.

I don't consider conditions where queries don't vectorize to be negative (execution) tests.  The
queries succeed in row mode.
