Hi Shengkai,

Thank you for driving this FLIP! I think this is a good way to
close this gap on the short-term until FLIP-316 can be finished.

I would only like to add one thing: YARN has a `yarn.ship-files`
config option that ships local or DFS files/directories to the
YARN cluster [1].

Best,
Ferenc
