[SPARK-6299][CORE] ClassNotFoundException in standalone mode when running groupByKey with class defined in REPL
```
case class ClassA(value: String)
val rdd = sc.parallelize(List(("k1", ClassA("v1")), ("k1", ClassA("v2")) ))
rdd.groupByKey.collect
```
This code used to be throw exception in spark-shell, because while shuffling ```JavaSerializer```uses ```defaultClassLoader``` which was defined like ```env.serializer.setDefaultClassLoader(urlClassLoader)```.
It should be ```env.serializer.setDefaultClassLoader(replClassLoader)```, like
```
override def run() {
val deserializeStartTime = System.currentTimeMillis()
Thread.currentThread.setContextClassLoader(replClassLoader)
```
in TaskRunner.
When ```replClassLoader``` cannot be defined, it's identical with ```urlClassLoader```
