titleQuoted Identifiers in Version 0.13.0+

As of Hive 0.13.0, user and role names may optionally be surrounded by backtick characters (`) when the configuration parameter hive.support.quoted.identifiers is set to column (default value). All Unicode characters are permitted in the quoted identifiers, with double backticks (``) representing a backtick character. However when hive.support.quoted.identifiers is set to none, or in Hive 0.12.0 and earlier, only alphanumeric and underscore characters are permitted in user names and role names.

For details, see HIVE-6013 and Supporting Quoted Identifiers in Column Names.

As of Hive 0.14, user may be optionally surrounded by backtick characters (`) irrespective of the hive.support.quoted.identifiers  setting.
