Louis Traynard created SPARK-14662:
--------------------------------------
Summary: LinearRegressionModel uses only default parameters if
yStd is 0
Key: SPARK-14662
URL: https://issues.apache.org/jira/browse/SPARK-14662
Project: Spark
Issue Type: Bug
Components: ML
Reporter: Louis Traynard
Priority: Minor
In the (rare) case when yStd is 0 in LinearRegression, parameters are not
copied immediately to the created LinearRegressionModel instance. But they
should (as in all other cases), because currently only the default column names
are used in and returned by model.findSummaryModelAndPredictionCol(), which
leads to schema validation errors.
The fix is two lines and should not be hard to check & apply.
