Subject [jira] [Commented] (HIVE-4945) Make RLIKE/REGEXP run end-to-end by updating VectorizationContext
Date Mon, 12 Aug 2013 11:15:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13736761#comment-13736761

Teddy Choi commented on HIVE-4945:
----------------------------------

While writing this code, I found that even if the query was not running with vectorization
expressions, it returns the same .q.out file. So it makes hard to check that vectorization
expressions were used or not.

There is a way to check it. If vectorized expressions were used, ExecDriver#job#getMapperClass()
returns VectorExecMapper#class after calling ExecDriver#execute(). Otherwise, getMapperClass()
returns ExecMapper#class.
