Hello, Consider the following test: https://github.com/apache/tez/blob/90c8195de0ddee9da3d4cd07519c8e287c85ad50/tez-api/src/test/java/org/apache/tez/dag/api/TestDAGVerify.java#L779-L831
For the VertexGroup uv23, we have a total of 4 tasks, 2 coming from v2, and 2 coming from v3. This is connected to v5, which in the test, we assert has a total of 2 tasks, after DAG.verify runs (which infers parallelism for one to one edges). However, isn't the expected number of tasks in v5 supposed to be 4, as uv23 acts as a union? Thanks, Adrian
