-----------------------------------------------
[~nobleyd] Do you mean the stop command did not succeed and the previous
checkpoint was deleted? It seems weird to me. could you please share more logs
with us(jm and tm log, it's better to enable debug log).
> Do not delete old checkpoints when stop the job.

> Project: Flink
> Issue Type: Improvement
> Components: Client / Job Submission, Runtime / Checkpointing
> Reporter: nobleyd
> Priority: Major
>
> When stop flink job using 'flink stop jobId', the checkpoints data is
> deleted.
> When the stop action is not succeed or failed because of some unknown errors,
> sometimes the job resumes using the latest checkpoint, while sometimes it
> just fails, and the checkpoints data is gone.
> You may say why I need these checkpoints since I stop the job and a savepoint
> will be generated. For example, my job uses a kafka source, while the kafka
> missed some data, and I want to stop the job and resume it using an old
> checkpoint. Anyway, I mean sometimes the action stop is failed and the
> checkpoint data is also deleted, which is not good.
> This feature is different from the case 'flink cancel jobId' or 'flink
> savepoint jobId', which won't delete the checkpoint data.
