> Project: Spark
> Issue Type: Bug
> Components: ML
> Affects Versions: 2.0.1, 2.1.0
> Reporter: Weichen Xu

> Currently,
> LinearRegression LogisticRegression AFTSuvivalRegression' s `fit` interface will persist the `dataframe` passed in if it is not persisted.
> but when possible exception throws, it won't be unpersist.
> As `fit` is a public interface, it is better to unpersist the parameter object passed in in any case, if it do `persist` internally.
