[jira] [Created] (FLINK-21080) Identify JobVertex containing legacy
source operators and abort checkpoint with legacy source operators
partially finished
Yun Gao created FLINK-21080:
-------------------------------
Summary: Identify JobVertex containing legacy source operators and abort checkpoint with legacy source operators partially finished
Key: FLINK-21080
URL: https://issues.apache.org/jira/browse/FLINK-21080
Project: Flink
Issue Type: Sub-task
Reporter: Yun Gao
Most legacy source operators would record the offset for each partitions, and after recovery it would read from the recorded offset. 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.
