Steven Zhen Wu updated FLINK-19816: ----------------------------------- Description: h2. Summary Upon failure, it seems that Flink didn't restore from the last completed checkpoint. Instead, it restored from a very old checkpoint. As a result, Kafka offsets are invalid and caused the job to replay from the beginning as Kafka consumer "auto.offset.reset" was set to "EARLIEST". This is an embarrassingly parallel stateless job. Parallelism is over 1,000. I have the full log file from jobmanager at INFO level available upon request. h2.
