[jira] [Updated] (HIVE-8391) Comparion between TIMESTAMP and Integer types goes to STRING as "common comparison denominator" instead of a numeric type

     [ https://issues.apache.org/jira/browse/HIVE-8391?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Dere updated HIVE-8391:
-----------------------------
    Attachment: HIVE-8391.1.patch

I think this patch should address this issue - the common class between timestamp/numeric (up to double) will be treated as double. Are there any Hive scholars that can confirm that this is the correct behavior?
