----------------------------------------
Summary: Random Forest Classifier should expose
intermediateRDDStorageLevel similar to ALS
Key: SPARK-20723
URL: https://issues.apache.org/jira/browse/SPARK-20723
Project: Spark
Issue Type: New Feature
Components: ML
Affects Versions: 2.3.0
Reporter: madhukara phatak
Priority: Minor
Currently Random Forest implementation cache as the intermediatery data using
*MEMORY_AND_DISK* storage level. This creates issues in low memory scenarios.
So we should expose an expert param *intermediateRDDStorageLevel* which allows
user to customise the storage level. This is similar to als options like
specified in below jira
