   I have a fix for this issue for anyone else who runs into it when re-loading a model. It seems like the default option should be saved in the params map but is not. So load your model as follows. 
   
   `
   val lrModel = LinearRegressionModel.load("/you_model_path")
   //can view your model params with 
   // lrModel.extractParamMap
   lrModel.set(lrModel.loss, "squaredError")
   `
