Sean Owen commented on SPARK-16801:
-----------------------------------
{{clearThreshold}} is unrelated to vectors entirely. It's a threshold on the
dot product. You'd have to provide a specific example, but I don't think this
can be the actual problem if there is one.
> clearThreshold does not work for SparseVector
