Bobby Wang updated SPARK-50844:
-------------------------------
    Description: 
Currently, Since most of models from Spark.ml doesn't have a public 
no-arguments constructor which results in the model couldn't be loaded by 
ServiceLoader. 

Currently, in order to load a model in connect ML, we're using reflection way 
which seems a little bit of unsafe.
