Summary: Adding API to SparkConf for kryo serializers registration
Key: SPARK-9595
URL: https://issues.apache.org/jira/browse/SPARK-9595
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.4.1, 1.3.1
Reporter: John Chen
Priority: Minor
Currently SparkConf has a registerKryoClasses API for kryo registration.
However, this only works when you register classes. If you want to register
customized kryo serializers, you'll have to extend the KryoSerializer class and
write some codes.
This is not only very inconvenient, but also require the registration to be
done in compile-time, which is not always possible. Thus, I suggest another API
to SparkConf for registering customized kryo serializers. It could be like this:
def registerKryoSerializers(serializers: Map[Class[_], Serializer]): SparkConf
