Johannes Günther commented on SPARK-10510:
------------------------------------------
If I understand It correctly from reading the Kryo Documentation you just
implement your Serializer class.
But from the first look there is not method to register this custom serializer.
But you if you have one or two classes to serialize with a specific schema
extend your object with
{code:SomeClass.java|borderStyle=solid}
public class SomeClass implements KryoSerializable {
// ...
public void write (Kryo kryo, Output output) {
// ...
}
public void read (Kryo kryo, Input input) {
// ...
}
}
{code}
You can register that class now with SparkConf.registerKryoClasses.
