------------------------------------

             Summary: GradientBoostingSuite takes more than 1 minute to finish
                 Key: SPARK-4347
                 URL: https://issues.apache.org/jira/browse/SPARK-4347
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.2.0
            Reporter: Xiangrui Meng


On a MacBook Pro:

{code}
[info] GradientBoostingSuite:
[info] - Regression with continuous features: SquaredError (22 seconds, 875 milliseconds)
[info] - Regression with continuous features: Absolute Error (25 seconds, 652 milliseconds)
[info] - Binary classification with continuous features: Log Loss (26 seconds, 604 milliseconds)
{code}

Maybe we can reduce the size of test data and make it faster.
