Subject [jira] [Commented] (HIVE-10533) CBO (Calcite Return Path): Join to MultiJoin support for outer joins
Date Wed, 27 May 2015 18:46:19 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14561479#comment-14561479

Jesus Camacho Rodriguez commented on HIVE-10533:
------------------------------------------------

[~ashutoshc], I just created the RB entry. Current patch only merges left-deep join trees;
we are going to discuss with [~vikram.dixit] and [~jpullokkaran] to see if/how we extend it
for other cases.
