>                 Key: SPARK-16835
>                 URL: https://issues.apache.org/jira/browse/SPARK-16835
>             Project: Spark
>          Issue Type: Bug
>          Components: ML
>    Affects Versions: 2.0.1, 2.1.0
>            Reporter: Weichen Xu
>   Original Estimate: 24h
>  Remaining Estimate: 24h

> 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.
