Wouldn't it better to Vectorize `StringIndexer` and `OneHotEncoder`? Like
for instance `.na.fill` or `.na.replace` operate over the whole data set at
once instead of running it in a loop? I feel like even with this patch this
isn't scalable on lets say 1MM covariates (unless I'm missing something) as
this process isn't executed at all nodes/cores at the same time.
