[jira] [Commented] (HIVE-12479) Vectorization: Vectorized Date UDFs with up-stream Joins

["Gopal V (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-12479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15026558#comment-15026558 ] 

Gopal V commented on HIVE-12479:
--------------------------------

The batch.selectedInUse and col.isRepeating were interfering with each other's semantics.

Fix for all Date UDFS + added test-case with 1 value column, with isRepeating=true, isSelectedInUse=true & .selected[0] = 42;

After the fix, it should not be trying to read col[42], but should operate on col[0] because isRepeating is true.

> The row-counts expected with and without vectorization differ.
> The attached small-scale repro case produces 5 rows with vectorized multi-key joins and 53 rows without the vectorized join.
