[jira] [Commented] (HIVE-3403) user should not specify mapjoin to
perform sort-merge bucketed join
[ https://issues.apache.org/jira/browse/HIVE-3403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15719384#comment-15719384 ]
Lefty Leverenz commented on HIVE-3403:
--------------------------------------
Doc note: This adds *hive.auto.convert.sortmerge.join* and *hive.auto.convert.sortmerge.join.bigtable.selection.policy* to HiveConf.java in release 0.11.0, so they need to be documented in the wiki.
* [Configuration Properties -- Query and DDL Execution | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]
Added a TODOC11 label.

> Currently, in order to perform a sort merge bucketed join, the user needs
> to set hive.optimize.bucketmapjoin.sortedmerge to true, and also specify the
> mapjoin hint.
> The user should not specify any hints.
