> Project: Spark
> Issue Type: Bug
> Components: MLlib
> Reporter: Yu Ishikawa
> Priority: Minor
>
> We can set the invalid indices when constructing a SparseVector. We should
> validate the indices before the construction.
> It should be invalid, but we can make a SparseVector with below. It is not
> until we access the value with the index that an exception is raised.
> {code}
> Vectors.sparse(4, Array(100), Array(1.0))
