------------------------------
Summary: Add HasIntermediateStorageLevel shared param trait and apply to classification/clustering/regression estimators
Key: SPARK-57860
URL: https://issues.apache.org/jira/browse/SPARK-57860
Project: Spark
Issue Type: Sub-task
Components: MLlib
Affects Versions: 4.0.0
Reporter: Mao Li
Add a HasIntermediateStorageLevel trait to sharedParams.scala, following the same pattern
as other Has* param traits. Apply it to the following estimators that currently hardcode
StorageLevel.MEMORY_AND_DISK for intermediate dataset persistence:
Classification: LogisticRegression, LinearSVC, FMClassifier, OneVsRest
Clustering: KMeans, GaussianMixture, LDA
Regression: LinearRegression, AFTSurvivalRegression, FMRegressor, IsotonicRegression
Other: FPGrowth
Also update the corresponding PySpark classes.
Part of SPARK-47103.
