Subject [jira] [Commented] (HIVE-8052) Vectorization: min() on TimeStamp datatype fails with error "Vector aggregate not implemented: min for type: TIMESTAMP"
Date Fri, 19 Sep 2014 23:22:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14141530#comment-14141530
] 

Matt McCline commented on HIVE-8052:
------------------------------------


Problem was the loading of data into the test table (see new JIRA HIVE-8197).  Turning on
vectorization was moved to after the loading and MR and Tez query results now match.

> Changes in HIVE-5760 to make explicit when timestamp and date can be vectorized as Long
were accidentally to strict for min, max, count, etc.
