> Components: ML
> Reporter: yuhao yang
> Priority: Minor

> As we use ml.vector to replace mllib.vector in ml, users use mllib.vector as
> input column will get error. Yet some error message is confusing:
> s"Input column ${$(inputCol)} must be a vector column")
> The input column probably is already a vector of mllib. Update to avoid the
> confusion.
