java Apache Flink:NoSuchMethodError在提交Flink作业时出错

Question

我正在尝试向flink群集提交作业，但一直遇到以下错误：

2021-05-03 17:14:32
java.lang.NoSuchMethodError: org/apache/flink/api/common/state/OperatorStateStore.getSerializableListState(Ljava/lang/String;)Lorg/apache/flink/api/common/state/ListState; (loaded from file:/opt/flink/lib/flink-dist_2.11-1.11.3.jar by jdk.internal.loader.ClassLoaders$AppClassLoader@c7a20636) called from class org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumerBase (loaded from file:/tmp/blobStore-d962f26c-fc16-4ff4-89da-4d86ed60c35e/job_fdc8c054e20b751b6a6f549af602c3d2/blob_p-5fcb7b854786da736df1bbd47aa02017c714f655-34f669043602e72ef3faf32247ab2b17 by org.apache.flink.util.ChildFirstClassLoader@3952d030).

我相信这个问题与版本不匹配有关（我假设我使用的是卡夫卡连接器），但我还没有解决它。我已尝试将flink版本设置为与集群（1.11.3）相同，但错误仍然存在。我也不完全确定如何使用maven shade插件来解决这个问题。任何帮助都将不胜感激

在release notes for Flink 1.11中，它指出

Removal of deprecated state access methods (FLINK-17376)

We removed deprecated state access methods RuntimeContext#getFoldingState(), OperatorStateStore#getSerializableListState() and OperatorStateStore#getOperatorState(). This means that some code that was compiled against Flink 1.10 will not work with a Flink 1.11 cluster. An example of this is our Kafka connector which internally used OperatorStateStore.getSerializableListState.

在升级到Flink的新版本时，您应该始终希望重新编译用户JAR。不保证小版本更新（例如从1.10.x到1.11.y）之间的二进制兼容性。（在补丁发行版中引入突破性更改是不寻常的，但这种情况已经发生过一两次。）

概述：您的用户jar、其依赖项和集群所涉及的所有内容都应该使用相同版本的Flink
