[jira] [Created] (SPARK-1696) RowMatrix.dspr is not using parameter alpha for DenseVector

Anish Patel created SPARK-1696:
----------------------------------

             Summary: RowMatrix.dspr is not using parameter alpha for DenseVector
                 Key: SPARK-1696
                 URL: https://issues.apache.org/jira/browse/SPARK-1696
             Project: Spark
          Issue Type: Bug
          Components: MLlib
            Reporter: Anish Patel
            Priority: Minor


In the master branch, method dspr of RowMatrix takes parameter alpha, but does not use it when given a DenseVector.

This probably slid by because when method computeGramianMatrix calls dspr, it provides an alpha value of 1.0.
