As required by Apache Flink, please report bugs or new features on Apache Jira under the project Flink using component tag Flink CDC. You must have a JIRA account in order to log cases and issues. If you don’t have an ASF JIRA account, you can request one at the ASF Self-serve portal, account creation requires review by the PMC member of the application project, which normally takes one to two working days to be approved.

我使用Flink CDC 3.5.0 + Flink 1.20.0 + java 8，将cdc任务提交到k8s集群中，然后taskmaanger报错：

This issue has been closed because Flink CDC doesn't use GitHub issue trackers.
