If before a checkpoint > some subtasks are finished, the corresponding partition offsets would be > deserted in the checkpoint. Then if the job recover with this checkpoint, the > legacy source would re-discovery all the partitions and for those finished > tasks, the legacy source would re-read them since their offsets are not > recorded. > Therefore, we would like to fail the checkpoint if some legacy source > operators have part of subtasks finished. -- This message was sent by Atlassian Jira (v8.3.4#803005)
