Thanks.
Does it make sence to add ==/equals method for Vector with this (or same)
behavior?

Vector is an enhanced Array[Double]. You can compare it like
Array[Double]. E.g.,
scala val v1 = Vector(1.0, 2.0)
v1: org.apache.spark.util.Vector = (1.0, 2.0)
scala val v2 = Vector(1.0, 2.0)
v2: org.apache.spark.util.Vector = (1.0, 2.0)
scala val exactResult = v1.elements.sameElements(v2.elements) // exact
comparison
exactResult: Boolean = true
scala val delta = 1E-6
delta: Double = 1.0E-6
scala val inexactResult = v1.elements.length == v2.elements.length
v1.elements.zip(v2.elements).forall { case (x, y) = (x - y).abs delta }
// inexact comparison
inexactResult : Boolean = true

Hello. How should i better check two Vector's for equality?
val a = new Vector(Array(1))
val b = new Vector(Array(1))
println(a == b)
// false
