Derrick Burns updated SPARK-5186:
---------------------------------
Description:
The implementation of Vector.equals and Vector.hashCode are correct but slow
for SparseVectors that are truly sparse.
was:
The implementation of Vector.equals (and Vector.hashCode) is only correct for
DenseVectors. SparseVectors with different indices but the same values not
equal, but the indices are not considered in equals and hashCode.
> Vector.equals and Vector.hashCode are very inefficient
