报错信息:Exception in thread “Thread-5” java.lang.IllegalStateException: Trying to access closed classloader. Please check if you store classloaders directly or indirectly in static fields. If the stacktrace suggests that the leak occurs in a third party library and cannot be fixed immediately, you can disable this check with the configuration ‘classloader.check-leaked-classloader’.
类加载器相关的报错，可能是类加载器问题
您可以使用配置“classloader.check-leaked-classloader”禁用此检查。
编辑flink-conf.yaml
增加 ：classloader.check-leaked-classloader: false ， 保存后重启任务即可
