Bikas Saha commented on TEZ-1190: --------------------------------- VertexGroup can only be the source of a group input edge and not the destination. So I dont think Pig could have made VG1 the destination of 2 input edges. Perhaps what is happening here is that there are 2 vertices inside VG1 which are receiving the 2 inputs from V1? > Allow multiple edges between two vertexes > ----------------------------------------- > > Key: TEZ-1190 > URL: https://issues.apache.org/jira/browse/TEZ-1190 > Project: Apache Tez > Issue Type: Bug > Reporter: Daniel Dai > > This will be helpful in some scenario. In particular example, we can merge > two small pipelines together in one pair of vertex. Note it is possible the > edge type between the two vertexes are different. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
