Solve least square problem of the form min norm(A x - b)^2^ + lambda * n * norm(x)^2 ?

[Jaonary Rabarisoa]

Dear all,

Is there a least square solver based on DistributedMatrix that we can use
out of the box in the current (or the master) version of spark ?
It seems that the only least square solver available in spark is private to
recommender package.


Cheers,

Jao
