Joseph K. Bradley updated SPARK-20043:
--------------------------------------
    Summary: Decision Tree loader does not recognize impurity "Gini" and 
"Entropy" on ML random forest and decision. Only "gini" and "entropy" (in lower 
case) are accepted  (was: CrossValidatorModel loader does not recognize 
impurity "Gini" and "Entropy" on ML random forest and decision. Only "gini" and 
"entropy" (in lower case) are accepted)

> I saved a CrossValidatorModel with a decision tree and a random forest. I use 
> Paramgrid to test "gini" and "entropy" impurity. CrossValidatorModel are not 
> able to load the saved model, when impurity are written not in lowercase. I 
> obtain an error from Spark "impurity Gini (Entropy) not recognized.
