public interface Saveable
Trait for models and transformers which may be saved as files. This should be inherited by the class which implements model instances.
void save(SparkContext sc, String path)
This saves: - human-readable (JSON) model metadata to path/metadata/ - Parquet formatted data to path/data/
The model may be loaded using
sc - Spark context used to save model data.
path - Path specifying the directory in which to save this model.
If the directory already exists, this method throws an exception.
