-------------------------------------------
We'll need to retarget this for 2.4, but I'll mark myself as shepherd to try to make sure it gets in.

> Issue Type: Improvement
> Components: ML, PySpark
> 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)

> but most other decision trees allow
> {{regressor.getMaxDepth()}}
