[BUG] LinearRegressionModel use default parameters if yStd is 0 ## What changes were proposed in this pull request? In the (rare) case where yStd is 0 in LinearRegression, parameters are not copied immediately to the created LinearRegressionModel instance, but they should (as in all other cases), because now the default column names are used in and returned by model.findSummaryModelAndPredictionCol(), which leads to schema validation errors. ## How was this patch tested? some simple manual tests You can merge this pull request into a Git repository by running: $ git pull https://github.com/shkdee/spark patch-1 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/12415.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #12415 ---- commit c05db63f1b6af0bdc6f0c277679e53a01913b3c5 Author: Louis Traynard <shk...@users.noreply.github.com> Date: 2016-04-15T10:06:01Z [BUG] copy parameters to LinearRegressionModel instance In the (rare) case where yStd is 0 in LinearRegression, parameters are not copied immediately to the created LinearRegressionModel instance, but they should (as in all other cases), because now the default column names are used in and returned by model.findSummaryModelAndPredictionCol(), which leads to schema validation errors. ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
