[jira] [Commented] (HIVE-8434) Vectorization logic using wrong values for DATE and TIMESTAMP partitioning columns in vectorized row batches...

    [ https://issues.apache.org/jira/browse/HIVE-8434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16049759#comment-16049759 ] 

Charles Pritchard commented on HIVE-8434:
-----------------------------------------

Hit this in 1.2.1 when using MONTH(CAST(datestr_partitioncol as date)) on select and group by -- gives unstable results. Seeing a lot of 7 and 31.
