Revoke a user's access rights.
Syntax: revoke  [,  [,  [, ]]]
Syntax: revoke , <@namespace>

Note: Groups and users access are revoked in the same way, but groups are prefixed with an '@'
      character. Tables and namespaces are specified the same way, but namespaces are
      prefixed with an '@' character.

For example:

    hbase> revoke 'bobsmith'
    hbase> revoke '@admins'
    hbase> revoke 'bobsmith', '@ns1'
    hbase> revoke 'bobsmith', 't1', 'f1', 'col1'
    hbase> revoke 'bobsmith', 'ns1:t1', 'f1', 'col1'
EOF
      end

      def command(user, table_name = nil, family = nil, qualifier = nil)
        security_admin.revoke(user, table_name, family, qualifier)
      end
    end
  end
