> It appears that the public {{Row}}'s hashCode is no longer overridden as of Spark 1.5.0:
> {code}
> val x = Row("Hello")
> val y = Row("Hello")
> println(x == y)
> println(x.hashCode)
> println(y.hashCode)
> {code}
> outputs
> {code}
> true
> 1032103993
> 1346393532
> {code}
> This violates the hashCode/equals contract.
> I discovered this because it broke tests in the {{spark-avro}} library.
