> [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 comma-separated decimal format to output the encoded
> contents. This way is rare when the data is in binary. This could be a common
> issue when we use Dataset API.
> For example,
> {code}
> implicit val kryoEncoder = Encoders.kryo[KryoClassData]
> val ds = Seq(KryoClassData("a", 1), KryoClassData("b", 2),
> KryoClassData("c", 3)).toDS()
> ds.show(20, false);
> {code}
