Hi Imran,

  I have been swamped with other issues to resolve (related to our use of spark), but once that is done, I have promised Matei to port our changes (including everything already in yarn branch) to trunk.
That should hopefully address a bunch of issues.

Unfortunately, I do not have a clear timeline on when that would be possible - definitely only after 0.7 is released.
Apologies for the delay !

Regards,
Mridul
