У меня есть исключение, когда я запускаю свой код в кластере flink. Я считаю, что проблема заключается в перекрытии файлов .jar во время исполнения с maven.
Я могу запустить код de в локальном режиме, но когда я запускаю программу на клиенте kafka, это выдает исключение, чтобы попытаться загрузить de "javax / manangent / MBeanServer".
это исключение, созданное кластером de flink:
java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/flink/runtime/execution/librarycache/FlinkUserCodeClassLoaders$ChildFirstClassLoader) previously initiated loading for a different type with name "javax/management/MBeanServer"
