>             Project: Flink
>          Issue Type: Bug
>          Components: Library / Machine Learning
>    Affects Versions: ml-2.2.0

>            Priority: Major

> The current implementation did not consider following case:
> When distanceThreshold not null and set as a large value, all data points are supposed to be assigned into a single cluster.
>  
> In this case, we should stop training when the number of the active clusters is one.
