difference about FMClassifier in spark3.0

[shuDaoNan9]

I find FMClassifier in spark3, but I don't know what formate my featuresCol should be. I used my gbdt feature, but the result AUC is bad.

some of my code: val classifier = new FMClassifier() .setLabelCol("click") .setFeaturesCol("gbdtFeature") .setPredictionCol("predictClick") .setProbabilityCol("probabilitys")

thank in advance!
