Subject [jira] [Commented] (HIVE-3403) user should not specify mapjoin to perform sort-merge bucketed join
Date Thu, 20 Sep 2012 05:18:07 GMT

Navis commented on HIVE-3403:
-----------------------------

@Namit Jain;
I've just released from HIVE-3381. Let's start looking into this.

I think this patch tries to solve two issues simultaneously. One is for merging two config
to single one as mentioned above, and the other is for extending SMBOptimizer by additional
conversion rule (JOIN to SMBJOIN directly), which is great. Is it possible to use it with
hive.auto.convert.join=true?

> 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.
