------------------------------------
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.
