> Today 1-1 dependencies are affinitized by creating a task location hint with the producer task container id. It can be created by affinitizing to the producer task-index+vertexname combination instead and internally Tez can map it to the container. This also allows this dependency to be specified before the container is assigned. This allows the dependency to be generic.
