-------------------------------

             Summary: [SQL] Display the binary/encoded values
                 Key: SPARK-12164
                 URL: https://issues.apache.org/jira/browse/SPARK-12164
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.6.0
            Reporter: Xiao Li


So far, we are using decimal format to output the encoded contents. This way is rare when the data is in binary. 

For example, 
    implicit val kryoEncoder = Encoders.kryo[KryoClassData]
    val ds = Seq(KryoClassData("a", 1), KryoClassData("b", 2), KryoClassData("c", 3)).toDS()
    ds.show(20, false);
