Subject [jira] [Created] (SPARK-17747) WeightCol support non-double datetypes
Date Fri, 30 Sep 2016 14:05:24 GMT
zhengruifeng created SPARK-17747:
------------------------------------

             Summary: WeightCol support non-double datetypes
                 Key: SPARK-17747
                 URL: https://issues.apache.org/jira/browse/SPARK-17747
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: zhengruifeng


WeightCol only support double type now, which should fit with other numeric types, such as
Int.
