Yanbo Liang commented on SPARK-9793:
------------------------------------
[~josephkb] I think we can override the "Vector.__eq__" of Python like what
Vector.equals() of Scala does, then it can compare DenseVector with
SparseVector. If this make sense, I can submit a patch tomorrow.
> PySpark DenseVector, SparseVector should override __eq__

> Key: SPARK-9793
> URL: https://issues.apache.org/jira/browse/SPARK-9793
> Project: Spark
> Issue Type: Bug
> Components: ML, PySpark
> Affects Versions: 1.5.0
> Reporter: Joseph K. Bradley
> Priority: Critical
>
> See [SPARK-9750].
> 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.)
