distributed choleksy on spark?

I'm wondering if anyone has done distributed choleksy decomposition on Spark.
I need to do it on a large matrix (200k x 200k) which would not fit on 1
machine.

So far I've found:
https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/linalg/CholeskyDecomposition.scala
and SystemML, but both seem to be single-node implementations.

Any information on the issue is helpful! Thanks.
