Subject [jira] [Commented] (HIVE-10072) Add vectorization support for Hybrid Grace Hash Join
Date Wed, 25 Mar 2015 01:20:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14379097#comment-14379097

Matt McCline commented on HIVE-10072:
-------------------------------------

Looks like you had VectorMapJoinOperator spillBigTableRow call super.spillBigTableRow instead
of duplicating the code to determine spill container, etc.  Good.
And added a a HybridGrace test for vectorization.

Initially I though perhaps the q file should have the "vector_" prefix.  However, giving it
is Tez only -- and there are other Tez tests that have vectorization portions -- I am fine
with patch #3 as it is.
