## What changes were proposed in this pull request? In both cases, the input `DataFrame` schema must contain only the information that's required for the matrix object, so a vector column in the case of `RowMatrix` and long and vector columns for `IndexedRowMatrix`. ## How was this patch tested? Unit tests that verify: - `RowMatrix` and `IndexedRowMatrix` can be created from `DataFrame`s - If the schema does not match expectations, we throw an `IllegalArgumentException` Please review https://spark.apache.org/contributing.html before opening a pull request.
