Bikas Saha commented on TEZ-2221:
---------------------------------
If VertexGroup("A", v1) and VertexGroup("B", v1) and connecting both to v2
allows for multiple edges between v1 and v2 then we should allow 2. Thats the
simplest solution to the multiple edges issues. But this needs to be verified.
> VertexGroup name should be unqiue
