> Vertices with shuffle input and MRInput choose RootInputVertexManager (and not ShuffleVertexManager) and start containers and tasks immediately. In this scenario, resources can be wasted since they do not respect tez.shuffle-vertex-manager.min-src-fraction tez.shuffle-vertex-manager.max-src-fraction.
