bq. Guessing this isn't the final patch, since VertexManager, TezConf,
VertexManagerPlugin are changing here?
No, this isn't the final patch, but I'd like feedback on the approach before I
stress test it and clean it up.
Basically, I just want feedback on [this

and whether you think that this approach is ok.

>
> 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.
