Subject [jira] [Commented] (HIVE-8488) hash() doesn't match between string and char/varchar
Date Fri, 17 Oct 2014 03:06:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14174685#comment-14174685
] 

Jason Dere commented on HIVE-8488:
----------------------------------

Test failure are because the test queries use sum(hash()), and of course hash() behavior has
changed in this patch. Fix would be to simply update the diffs, but just goes to highlight
that this is breaking existing hash() behavior for char/varchar.

> This may throw off users expecting string/varchar/char types to be fairly interchangeable.
