@noel-smith could you review it when you have time? Thanks!

@yu-iskw Could you please fix the conflicts?

@noel-smith Will you be able to review this? If not, let me know, and I'll review it.

Thanks!

Hi @jkbradley - the version numbers look OK - but I've been unable to get the Scala API docs building in my environment (not just this branch - I get the same problems on master) - so I can't fully verify it.

If you can review it locally - that would probably be quicker in this case.

[yu-iskw]

Sure. I'll resolve the conflicts by rebaseing master. Just a minute!

@jkbradley I have rebased master.

@noel-smith could you take a look when you have time?

[jkbradley]

I'll review this now. @noel-smith I generally just look at the spark docs online to do this.

[jkbradley]

uid was added in 1.4 (so same for the constructor)

[jkbradley]

That should be it!
