What happened

The function implemented by the seatunnel task is to synchronize data from Kafka to ES. When the Seatunnel program restarts abnormally, it cannot restart the task from the checkpoint of Flink. The seatunnel task will continue to restart until the taskmanager crashes. This issue occurs when deploying Flink in both k8s and non k8s scenarios.

SeaTunnel Version

SeaTunnel 2.3.0 kafka 2.12-2.2.0 es 8.5
