How can I set the Flink Job Id to enable flink checkpoint

[wangpeibin]

hello,

    When I enable the checkpoint in flink job, I found that flink have saved the checkpoint to the dir such as ${statebackend}/${jobId}. but after I restart the flink job, the  job id is changed, so that the state does not restore correctly.
    How can I set the Flink Job Id in code?

Hi,

for starting a job from the state of a previous job you should look into savepoints: https://ci.apache.org/projects/flink/flink-docs-release-1.6/ops/state/savepoints.html

Checkpoints are only meant for faul tolerance within one execution of a job.

Best,
