[jira] [Created] (SPARK-17950) Match SparseVector behavior with DenseVector

AbderRahman Sobh created SPARK-17950:
----------------------------------------

             Summary: Match SparseVector behavior with DenseVector
                 Key: SPARK-17950
                 URL: https://issues.apache.org/jira/browse/SPARK-17950
             Project: Spark
          Issue Type: Improvement
          Components: MLlib, PySpark
    Affects Versions: 2.0.1
            Reporter: AbderRahman Sobh
            Priority: Minor


Simply added the `__getattr__` to SparseVector that DenseVector has, but calls self.toArray() instead of storing a vector all the time in self.array

This allows for use of numpy functions on the values of a SparseVector in the same direct way that users interact with DenseVectors.
 i.e. you can simply call SparseVector.mean() to average the values in the entire vector.
