Joseph K. Bradley updated SPARK-9793:
-------------------------------------
    Comment: was deleted

(was: I agree, we can.  However, we should be careful to make sure the 
{{__hash__}} method matches the semantics: 
[https://docs.python.org/2/reference/datamodel.html#object.__hash__])

> PySpark DenseVector, SparseVector should override __eq__

> PySpark DenseVector and SparseVector do not override the equality operator 
> properly.  They should use semantics, not representation, for comparison.  
> (This is what Scala currently does.)
