flink问题

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'.

解决办法： 在 flink 配置文件里 flink-conf.yaml设置
classloader.check-leaked-classloader: false
