org.apache.spark.SparkException: Task not serializable] with root cause

18/11/08 11:27:26 ERROR [dispatcherServlet]: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.apache.spark.SparkException: Task not serializable] with root cause

此异常出现的原因是类中存在未序列化的成员变量

---

解决方法：类实现serializable接口，将类中不需要序列化的成员变量使用transient关键字修饰。
