      # migration: wdavidw 170911, this is the same as the connection.assert call just above
      # @connection.assert
      #   header: 'Port'
      #   server: options.hive_site['hive.metastore.uris']
      #     .split(',')
      #     .map (uri) ->
      #       {fqdn, port} = url.parse uri
      #       host: fqdn, port: port
      #     .filter (server) ->
      #       server.fqdn is options.fqdn
