Hi Yun, Thank you so much for you suggestion.
(1) The job couldn’t restore from the last checkpoint. The exception is in my original email. (2) No, I didn’t change any multipart upload settings. (3) The file is gone. I have another batch process that reads Flink output s3 bucket and pushes objects to another bucket. Upon success read and write, The batch job will delete the file. What’s puzzling me is if Flink hasn’t successfully commit the multipart file, it should not be visible to the batch job. It looks the situation is while Flink tried to commit the multipart file, it crashed and restarted. The file is committed on s3 successfully, but not acknowledge recorded on Flink side. In between, the batch job consumed the file. I don’t know if that’s possible.
