Thanks for the background on this.

I got schooled offline too about the heaviness of the dependencies.

This is a good idea (to the extend I understand your proposal). Long term, we'd like YARN
UI2 to replace current UI, so it shouldn't be optionally build and hence the build should
be fast. Let me track this separately as a non-blocker.
