@andrewor14 Sorry for the mess up, I kept thinking the code was ready just 
needed to rebase and address comments. The rebase and comments did cause some 
style problems in the end, will be more careful next time. I took a pass again 
and I don't see anything any more. PTAL when you can.

in the future I will keep minor refactors like this separate from this 
patch. It's distracting to the reviewer and is not needed to fix SPARK-10749.

Ah yes I originally changed it because we changed the MesosSchedulerUtils 
return type as I rebased, but realized now I don't have to. I'm fixing it now.

I looked for the places where this is used. All you're doing is passing 
this java list into `scheduleTasks`, where you internally converts it back to 
scala again, and using it at the end of this method to decline offers, where 
you convert it back to scala anyway. You really don't need to make this 
`asJava` again.

We already have some shared logic of using multiple resources from 
different roles, it just wasn't plugged in when I wrote the cluster scheduler.
I think now we have a refactored coarse grained scheduler, we can take a 
step back and refactor both of these so a scheduler can have pluggable pieces 
when it comes to launching tasks and placing resources, etc. For now I think 
this PR is still valid that we just want to plug in the existing multiple role 
logic into cluster scheduler.

Actually you're right we're just returning the value as-is, we can remove

Schedule tasks returns the remaining offers after using them, after looking 
at this I think I can refactor it so we don't have to make it immutable.

similarly I don't get the point of assigning this var every time you call

@tnachen I also don't get it. If the caller called us with `currentOffers`, 
they already have access to it, so what's the point in returning them here? 
AFAIK we don't mutate this list in this method

@tnachen echoing my comment from another PR: it seems that this feature is 
already supported in client mode but not in cluster mode. Is there something we 
can do about this divergence in behavior? Is there some duplicate code to clean 
up so we don't run into something like this in the future?

Agree with `Nil ++`. Regarding Java <-> Scala conversions, I think this 
change is a net positive: removed around 9 calls to asJava and introduced only 
3 asScala. :)

@tnachen, this PR would need to be rebased on master. At any rate, if there 
are fixes in cluster-mode that make it work now, they are not part of this PR 
yet.

@tnachen I don't understand, `conf.getOption(...).toList` returns `Nil`, 
but you can append to an empty list can't you?

So, I like the code as it is now. I'm having trouble running Spark on Mesos 
in cluster mode, as always, so I didn't manage to test it, but that's most 
likely unrelated to code changes here. How did you test it?

What if the offer was already `used` here? One more reason to get rid of 
the `used` field altogether. Make this method assume `currentOffers` are all 
for the taking (as it does now), and returns all the remaining offers.

It seems wrong to return all original offers. Why not filter out the `used` 
ones? Callers of this method already do that, so you could get rid of the 
`used` field and simply filter out here. It will simplify reasoning everywhere.

You don't need `toList.asJava`. `asJava` is enough, and saves a round of

I think a for-comprehension would be slightly more efficient, though it's 
not a big deal.

```
for { o <- currentOffers.asScala if !o.used } driver.declineOffer(o.offerId)
```

`filter` creates an intermediate collection, while inside a for this can be 
fused into only one traversal.
