Lefty Leverenz commented on HIVE-5978:
--------------------------------------

Oh, just realized the wiki has a vectorization design doc now:  
[https://cwiki.apache.org/confluence/display/Hive/Vectorized+Query+Execution].  
It links to HIVE-4160 for the complete doc, very helpful.

ROLLUP isn't in the list of supported data types and operations, so perhaps its 
current lack of support is implied.  Should there be a list of supported 
aggregates?

> Rollups not supported in vector mode.

> Rollups are not supported in vector mode, the query should fail to vectorize. 
> A separate jira will be filed to implement rollups in vector mode.
