What changes were proposed in this pull request?
Change a data transformation while saving a Word2VecModel to happen with distributed data instead of local driver data.
How was this patch tested?
Unit tests for the ML sub-component still pass.
Running this patch against v2.2.0 in a fully distributed production cluster allows a 4.0G model to save and load correctly, where it would not do so without the patch.
