[jira] [Commented] (HIVE-5918) int / int division does not
vectorize due to type checks
[ https://issues.apache.org/jira/browse/HIVE-5918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838404#comment-13838404 ]
Sergey Shelukhin commented on HIVE-5918:
----------------------------------------
We discussed w/[~jnp]; the cause appears to be GenericUDFOPDivide::deriveResultExactTypeInfo, which is always decimal, from HIVE-5356. So, ints are exact types, and this goes to decimal. Didn't discuss solutions yet.
Ideally, we should have vectorization support for decimal.

> When I try to vectorize e.g. select cbigint / 0 from alltypesorc, (with some logging added), I get my logging
> physical.Vectorizer (Vectorizer.java:validateExprNodeDescRecursive(642)) - failed to validate type: decimal(25,6); (cbigint / 0)
