最近学习flink的时候写了最简单的一个demo,但是在测试的时候出现问题：
org.apache.flink.util.FlinkException: The TaskExecutor is shutting down.找了很久，也问了很多人基本没人给出答案。

在执行过程中，一开始流处理都可以执行，但是几秒后就停住了，经过debug和日志分析，Mini Cluster被停了。
但是相同的代码、依赖发给以前的同事又可以执行，所以猜测是环境问题，所以尝试各种环境的设置。
最后发现jdk版本有问题，我之前用得是jdk-8u181-linux-x64版本的,
由于一开始是正常的，完全没往jdk想。官网也没具体说jdk1.8哪个版本。坑了好久，也问了很多人。
最终的解决办法：
jdk 换成 jdk-8u231-windows-x64
jdk 换成 jdk-8u231-windows-x64
jdk 换成 jdk-8u231-windows-x64
