Hyukjin Kwon commented on SPARK-12259:
--------------------------------------
[~smilegator], I just happened to try to reproduce this.
{code}
import org.apache.spark.sql.Encoders
case class KryoClassData(st: String, i: Long)
implicit val kryoEncoder = Encoders.kryo[KryoClassData]
val ds = Seq( ( KryoClassData("a", 1), KryoClassData("b", 2) ) ).toDS()
ds.show()
{code}
It seems the codes above work fine now in the current master. Would this be
resolvable maybe?
