Solve system of linear equations in Spark

I have a system of linear equations in the form of Ax = b to solve in Spark. A is n by n b is n by 1 I represent 'A' in the form of IndexedRowMatrix or RowMatrix and 'b' in the form of DenseMatrix or DenseVector. How can I solve this system to calculate the 'x' vector? If the suggested solutio

Large-scale matrix inverse in Spark

How is the problem of large-scale matrix inversion approached in Apache Spark ? This linear algebra operation is obviously the very base of a lot of other algorithms (regression, classification, etc). However, I have not been able to find a Spark API on parallel implementation of matrix inversion.
