class SageMakerProtobufWriter extends OutputWriter

Writes rows of labeled vectors to Amazon protobuf Records encoded in RecordIO

By default, writes a label column of Doubles named "label" and a features column of Vector[Double]s named "features" to protobuf.

These column names can be reassigned with the option "labelColumnName" and "featuresColumnName".

To write records from a DataFrame in this file format, run dataframe.save .format("sagemaker") .option("labelColumnName", "myLabelColumn") .option("featuresColumnName", "myFeaturesColumn") .save("my_output_path")
