2.报错

Exception in thread "main" java.io.NotSerializableException: com.demo.bigdata.spark.core.test.Task
	at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)

	at com.demo.bigdata.spark.core.test.Driver$.main(Driver.scala:19)
	at com.demo.bigdata.spark.core.test.Driver.main(Driver.scala)

原因：对象没有序列化
解决：将对象序列化 继承 extends Serializable

class Task extends  Serializable {



}
