I think we can not override param in any ```set***``` function, since ML
pipeline API supports other param setting method like:
```
def fit(dataset: Dataset[_], paramMap: ParamMap): M = {
copy(paramMap).fit(dataset)
}
```
I think the only way to override param is at the start of ```fit```
function.
