[jira] [Created] (HIVE-15334) HIVE-13945 changed scale rules for division

             Summary: HIVE-13945 changed scale rules for division
                 Key: HIVE-15334
                 URL: https://issues.apache.org/jira/browse/HIVE-15334
             Project: Hive
          Issue Type: Bug
          Components: Types
            Reporter: Jason Dere


Looks like HIVE-13945 change the decimal division precision/scale rules - the explanation being "Changed the default decimal precision in division, not sure why it was so low by default." (https://issues.apache.org/jira/browse/HIVE-13945?focusedCommentId=15354403&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15354403)

As far as I can tell this causes decimal division to have a minimum scale of 18.
cc [~sershe] - the rules that were in place were based on the SQL Server precision/scale rules in https://msdn.microsoft.com/en-us/library/ms190476.aspx

I'd like to revert this change to precision/scale rules
