Xin Ren commented on SPARK-19282:
---------------------------------
sorry being naive, I'm not familiar with random forest, but is "max depth" an
important metrics/param of RF model?
> RandomForestRegressionModel should expose getMaxDepth
> -----------------------------------------------------

> Key: SPARK-19282
> URL: https://issues.apache.org/jira/browse/SPARK-19282
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 2.1.0
> Reporter: Nick Lothian
> Priority: Minor
>
> Currently it isn't clear hot to get the max depth of a
> RandomForestRegressionModel (eg, after doing a grid search)
> It is possible to call
> {{regressor._java_obj.getMaxDepth()}}
> but most other decision trees allow
> {{regressor.getMaxDepth()}}
