> Key: SPARK-14662
> URL: https://issues.apache.org/jira/browse/SPARK-14662
> Project: Spark
> Issue Type: Bug

> Priority: Minor
> Fix For: 2.0.0

> Original Estimate: 5m
> Remaining Estimate: 5m
>
> 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.
