> SparseVector created from Breeze Sparsevector has wrong size
> ------------------------------------------------------------
>
> Key: FLINK-2278
> URL: https://issues.apache.org/jira/browse/FLINK-2278
> Project: Flink
> Issue Type: Bug
> Reporter: Christoph Alt
> Labels: ML
>
> The following code doesn't return true when testing equality of two
> SparseVectors, one converted from a Breeze SparseVector.
> {code}
> val flinkVector = SparseVector.fromCOO(3, (1, 1.0), (2, 2.0))
> val breezeVector = linalg.SparseVector(3)(1 -> 1.0, 2 -> 2.0)
> flinkVector.equalsVector(breezeVector.fromBreeze)
> {code}
> The reason is that *fromBreeze* takes the number of non-zero elements
> *SparseVector.used* as size when creating a SparseVector instead of the
> dimensionality *SparseVector.length*.
