   @rdblue yes, the intention is just to make the fully resolved name available in the V2Relation so in the analysis step richer checks could be performed.
   
   The main reason that I went away from just Seq[String] is that the data frame reader seems to support loading from multiple paths at https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/DataFrameReader.scala#L191. In that case, a single Seq[String] would not be able to handle that.
   
   I will be on a vacation in the next two weeks. Will probably need to come back to this later.
