Hi,
When I try to save a pipeline model using spark ML (Java) , the following
exception is thrown.
java.lang.UnsupportedOperationException: Pipeline write will fail on this
Pipeline because it contains a stage which does not implement Writable.
Non-Writable stage: rfc_98f8c9e0bd04 of type class org.apache.spark.ml.
classification.Rand
Here is my code.
CrossValidatorModel model = cv.fit(trainingData);
model.write().overwrite().save("path");
PipelineModel model = pipeline.fit(trainingData);
PipelineModel model = pipeline.fit(trainingData);
model.write().overwrite().save("path");
How to resolve this?
Thank you!
