Subject [jira] [Commented] (HIVE-9081) Bucket mapjoin should use the new alias in posToAliasMap [Spark Branch]
Date Thu, 11 Dec 2014 18:17:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14242872#comment-14242872

Chao commented on HIVE-9081:
----------------------------

Maybe we can do it in {{MapJoinProcessor#convertJoinOpMapJoinOp}} - both auto conversion and
conversion with hint go through this method.

> In converting a mapjoin to a bucket mapjoin, the join aliases could be updated. So we
should update the posToAliasMap accordingly.
