[jira] [Commented] (HIVE-20733) GenericUDFOPEqualNS may not use = in plan descriptions

    [ https://issues.apache.org/jira/browse/HIVE-20733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16710335#comment-16710335 ] 

David Lavati commented on HIVE-20733:
-------------------------------------

As discussed, instead of "<=>" I'll use "IS NOT DISTINCT FROM", as that matches the SQL Standards.
