Sandy Ryza created SPARK-1813:
---------------------------------
Summary: Add a utility to SparkConf that makes using Kryo really
easy
Key: SPARK-1813
URL: https://issues.apache.org/jira/browse/SPARK-1813
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.0.0
Reporter: Sandy Ryza
It would be nice to have a method in SparkConf that makes it really easy to use
Kryo and register a set of classes. without defining you
Using Kryo currently requires all this:
{code}
import com.esotericsoftware.kryo.Kryo
import org.apache.spark.serializer.KryoRegistrator
class MyRegistrator extends KryoRegistrator {
override def registerClasses(kryo: Kryo) {
kryo.register(classOf[MyClass1])
kryo.register(classOf[MyClass2])
}
}
val conf = new SparkConf().setMaster(...).setAppName(...)
conf.set("spark.serializer", "org.apache.spark.serializer.KryoSerializer")
conf.set("spark.kryo.registrator", "mypackage.MyRegistrator")
val sc = new SparkContext(conf)
{code}
It would be nice if it just required this:
{code}
SparkConf.setKryo(Array(classOf[MyFirstClass, classOf[MySecond]))
{code}
