Christoph Alt created FLINK-2278:
------------------------------------
Summary: 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
The following code doesn't return true when testing equality of two
SparseVectors, one converted from a Breeze SparseVector.
`
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)
`
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*.
