MahmoudHanafy updated SPARK-13886:
----------------------------------
    Description: 
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}

Question: Can the key in MapType be of BinaryType ?

I want to contribute by fixing this issue.
