Subject [jira] [Updated] (HIVE-11684) Implement limit pushdown through outer join in CBO
Date Fri, 13 Nov 2015 17:33:11 GMT


Jesus Camacho Rodriguez updated HIVE-11684:
    Attachment: HIVE-11684.19.patch

HIVE-11684.19.patch addresses [~jpullokkaran]'s comments.

I also regenerated a few q files. Although the optimization is disabled by default, the changes
in the q files are due to the additions to the metadata providers (HiveRelMdSelectivity and
HiveRelMdRowCount) concerning left/right outer joins.
