Bikas Saha commented on TEZ-802:
--------------------------------
After TEZ-1013, we could improve the InputReady vertex manager to support
custom edges and then we could make it the default for custom edges.
Will add comments in the commit patch. Thanks for the review!

> Currently, task placement is determined by TaskLocationHints that are
> specified by the user in the API or during runtime. Everything else runs as
> without placement constraints. While this works for broadcase and
> scatter-gather edges, it does not work for 1-1 edges.
