Hi,



Have you checked if the error during normal execution, or right after failover?

Dear all：
          flink version is 1.12.4，kafka version is 1.1.1。topology is very 
simple ，source-->flatmap--->sink ，enable checkpoint，job will fail after a few 
hours 。 the error message is 


Caused by: org.apache.flink.streaming.connectors.kafka.FlinkKafkaException: 
Failed to send data to Kafka: The broker received an out of order sequence 
number.
