             Summary: Euclidean Distance Measure generates NAN distance values
                 Key: FLINK-29843
                 URL: https://issues.apache.org/jira/browse/FLINK-29843
             Project: Flink
          Issue Type: Bug
          Components: Library / Machine Learning
    Affects Versions: ml-2.1.0
            Reporter: Yunfeng Zhou


Currently Flink ML's `EuclideanDistanceMeasure.distance(...)` method might 
return a negative value as the distance between two vectors given the 
calculation accuracy of java doubles. This bug should be fixed to guarantee 
that the distance is a non-negative value.
