When using PairSCollectionFuctions rightOuterJoin()

The following error happens:

WARN org.apache.beam.sdk.Pipeline - The following transforms do not have stable unique names: rightOuterJoin@{Foo.scala:76}12, fooJoin2

Example code:


The problem seems to be around:

  def rightOuterJoin[W: ClassTag](that: SCollection[(K, W)])
  : SCollection[(K, (Option[V], W))] =
    ArtisanJoin.right(self.tfName, self, that)

where the same transform name is reused in another transform.
