Vinod Kumar Vavilapalli commented on YARN-422:
----------------------------------------------
I don't see any value in a wrapper around communication to a single NM. It does
hide-away the records, but what is useful and important is a library which
takes in a container given by RM and launches in whatever node it is allocated
on. In that sense, this "ContainerLauncher" library is what should be the
primary end-point for AM writers. If one wants to launch containers on a single
node, the same library should be enough.
And yeah, the more I think about, non-blocking APIs seem like must-have.
