Sean Owen commented on SPARK-3360:
----------------------------------
https://issues.apache.org/jira/browse/SPARK-3435 might be more relevant now.
I'm happy to propose a simple PR; is there an immediate need?
You don't need Vector.multiply(RowMatrix) really since it is either the same as
RowMatrix.multiply(Vector) or the same with the RowMatrix transposed.
> Add RowMatrix.multiply(Vector)
