Subject [jira] [Updated] (HIVE-8745) Joins on decimal keys return different results whether they are run as reduce join or map join
Date Fri, 07 Nov 2014 01:50:34 GMT

     [ https://issues.apache.org/jira/browse/HIVE-8745?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Dere updated HIVE-8745:
-----------------------------
    Attachment: HIVE-8745.3.patch

Patch v3, fix test failures. Per [~hagleitn], leaving HiveDecimal.equals() alone for now,
this is same behavior as it used to be.

considered the same value or not.
