How to save and load MLLib model in Apache Spark?

Question

I trained a classification model in Apache Spark (using pyspark). I stored the model in an object, LogisticRegressionModel. Now, I want to make pre

You can save your model by using the save method of mllib models.

# let lrm be a LogisticRegression Model
lrm.save(sc, "lrm_model.model")

After storing it you can load it in another application.

sameModel = LogisticRegressionModel.load(sc, "lrm_model.model")

As @zero323 stated before, there is another way to achieve this, and is by using the Predictive Model Markup Language (PMML).

is an XML-based file format developed by the Data Mining Group to provide a way for applications to describe and exchange models produced by data mining and machine learning algorithms.
