>             Project: Spark
>          Issue Type: Bug
>          Components: SQL

> There are multiple types that are supoprted by Spark SQL, One of them is ArrayType(Seq) which can be of any element type
> So it can be BinaryType(Array\[Byte\])
> In equals method in Row class, there is no handling for ArrayType of BinaryType.
> So for example:
> {code:xml}
> val a = Row( Seq( Array(1.toByte) ) )
> val b = Row( Seq( Array(1.toByte) ) )
> a.equals(b) // this will return false
> {code}
> Also, this doesn't work for MapType of BinaryType.
> {code:xml}
> val a = Row( Map(1 -> Array(1.toByte) ) )
> val b = Row( Map(1 -> Array(1.toByte) ) )
> a.equals(b) // this will return false
> {code}
> Question1: Can the key in MapType be of BinaryType ?
> Question2: Isn't there another way to handle BinaryType by using scala type instead of Array ?
> I want to contribute by fixing this issue.
