Reserved keywords are permitted as identifiers if you quote them as described in Supporting Quoted Identifiers in Column Names (version 0.13.0 and later, see HIVE-6013). Most of the keywords are reserved through HIVE-6617 in order to reduce the ambiguity in grammar (version 1.2.0 and later). There are two ways if the user still would like to use those reserved keywords as identifiers: (1) use quoted identifiers, (2) set hive.support.sql11.reserved.keywords=false.
