If your function is an anonymous inner class, consider the following:
+
- make the function a standalone class, or a static inner class.
- use a Java 8 lambda function.
Is your function is already a static class, check the fields that you assign when you create
an instance of the class. One of the fields most likely holds a non-serializable type.
+
- In Java, use a `RichFunction` and initialize the problematic fields in the `open()` method.
- In Scala, you can often simply use “lazy val” to defer initialization until the distributed execution happens. This may come at a minor performance cost. You can naturally also use a `RichFunction` in Scala.

If you see these problems in Flink 1.4+, one of the following may be true:
+
- You have a dependency version conflict within your application code. Make sure all your dependency versions are consistent.
- You are conflicting with a library that Flink cannot support via `child-first` classloading. Currently these are the
Scala standard library classes, as well as Flink's own classes, logging APIs, and any Hadoop core classes.

如果你使用的函数是匿名内部类，请考虑以下事项：
+
- 为函数构建独立的类或静态内部类。
- 使用 Java 8 lambda 函数。
如果函数已经是静态类，则在创建该类的实例时会检查该类的字段。其中很可能包含不可序列化类型的字段。
+
- 在 Java 中，使用 `RichFunction` 并且在 `open()` 方法中初始化有问题的字段。
- 在 Scala 中，你通常可以简单地使用 “lazy val” 声明来推迟初始化，直到分布式执行发生。这可能是一个较小的性能成本。你当然也可以在 Scala 中使用 `RichFunction`。

从 Flink 1.4.0 开始，在默认激活 `child-first` 类加载方式的情况下，相比 Flink core 所使用的依赖或类路径中的其他依赖（例如来自 Hadoop ）而言，应用程序 JAR 文件中的依赖更可能带有不同的版本。
如果你在 Flink 1.4 以上的版本中看到这些问题，则可能是属于以下某种情况：
+
- 你的程序代码中存在依赖项版本冲突，确保所有依赖项版本都一致。
- 你与一个 Flink 不能支持 `child-first` 类加载的库发生了冲突。目前会产生这种情况的有 Scala 标准库类、Flink 自己的类、日志 API 和所有的 Hadoop 核心类。
