GBM : Build GBM Model => Too many levels in response column! (java.lang.IllegalArgumentException) => Should display proper error message #13690

Steps to reproduce :

Dataset website : http://www.sigkdd.org/kdd-cup-2009-customer-relationship-prediction

1) h2o started locally 2) Import files from local for test and train : also copied to hdfs://mr-0xd6/datasets/KDD_Orange_Small

importFiles [ "/Users/nmadabhushi/Downloads/datasets/orange_small_train/orange_small_train.data","/Users/nmadabhushi/Downloads/datasets/orange_small_train/orange_small_train.data.cksum" ]

importFiles [ "/Users/nmadabhushi/Downloads/datasets/KDD/KDDOrange/orange_small_test/orange_small_test.data","/Users/nmadabhushi/Downloads/datasets/KDD/KDDOrange/orange_small_test/orange_small_test.data.cksum" ]

2) Parse data 3) Try to build GBM Model with train and validation against test(train and test data are provided on KDD website for orange)

: gives error below

Error calling POST /3/ModelBuilders.json/gbm/parameters with opts {"destination_key":"gbm-e6ef9443-34c5-4f1d-9e7b-31ab28e9d8fb","training_frame":"orange_small_train.hex","validation_frame":"orange_small_test.hex","dropNA20Cols":true,"response_column":"Var222","ntrees":50,"max_depth":5,"min_rows":10,"nbins":20,"learn_rate":0.1,"loss":"gaussian","balance_classes":false,"class_sampling_factors":null,"max_after_balance_size":5,"seed":0}
