[jira] [Created] (SPARK-19057) Instances' weight must be non-negative

zhengruifeng created SPARK-19057:
------------------------------------

             Summary: Instances' weight must be non-negative
                 Key: SPARK-19057
                 URL: https://issues.apache.org/jira/browse/SPARK-19057
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: zhengruifeng
            Priority: Trivial


It looks like that negative-weighted instances make no sense and can cause divergence in ml algs.
