Subject [jira] [Commented] (HIVE-5895) vectorization handles division by zero differently from normal execution
Date Tue, 26 Nov 2013 23:16:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13833208#comment-13833208
] 

Xuefu Zhang commented on HIVE-5895:
-----------------------------------

I understand that the current division can possibly return infinity or NaN. However, this
seems to me a bug (or bad behavior) rather than norm. To me, they provide no more information
than NULL. Such complication comes due to hive having no consistent error handling. HIVE-5348
and HIVE-5660 are to address those issues. For this particular case, I wouldn't be crying
if NULL is returned for both infinity or NaN, especially if it makes the life easier.
