Subject [jira] [Updated] (HIVE-8488) hash() doesn't match between string and char/varchar
Date Mon, 20 Oct 2014 23:32:33 GMT

     [ https://issues.apache.org/jira/browse/HIVE-8488?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Dere updated HIVE-8488:
-----------------------------
    Status: Open  (was: Patch Available)

Ok, that's not good.  Will have to find a way for this not to break existing tables clustered
on char/varchar columns if we do this change.
