can you change this to
```scala
// Allow the user to register their own classes by setting
spark.kryo.registrator
for (regCls <- registrator) {
logDebug("Running user registrator: " + regCls)
try {
val reg = Class.forName(regCls, true, classLoader).newInstance()
.asInstanceOf[KryoRegistrator]
reg.registerClasses(kryo)
} catch {
case e: Exception =>
throw new SparkException(s"Failed to invoke $regCls", e)
}
}
```
