[jira] [Commented] (FLINK-9043) Flink recover from checkpoint like
Spark Streaming
[ https://issues.apache.org/jira/browse/FLINK-9043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16407884#comment-16407884 ]
Stephan Ewen commented on FLINK-9043:
-------------------------------------
When a Flink job starts, you can tell it explicitly to start from a checkpoint (via checkpoint path) or savepoint.
That gives you the control to do exactly what you describe. In contrast, when starting a job without and further argument, Flink assumes it is a new job.
Both cases are valid use cases, that's why Flink makes it explicit whether a job starts from a checkpoint or starts as a new job.

> I know a flink job can reovery from checkpoint with restart strategy, but can not recovery as spark streaming jobs when job is starting.
> Every time, the submitted flink job is regarded as a new job, while , in the spark streaming job, which can detect the checkpoint directory first, and then recovery from the latest succeed one. However, Flink only can recovery until the job failed first, then retry with strategy.
>
> So, would flink support to recover from the checkpoint directly in a new job?
