Lefty Leverenz commented on HIVE-11703:

[~pxiong], the wiki needs to cover all Hive versions so I've restored REGEXP and RLIKE to
the non-reserved list with version information, and added version information in the reserved

> RegExp and RLike are treated as "precedenceEqualNegatableOperator" in Hive. They actually
come from MySQL. Both of them are not keywords in SQL2011. But they are reserved keywords
in MySQL. Making them reserved ones can eliminate the current 14 ambiguities that we have
in current Hive. If users still would like to use them as identifiers/function names, users
can "set;"
