Bowen Li updated FLINK-7566:
----------------------------
    Environment:     (was: Currently, if we want to start a Flink job from a checkpointing file, we have to run `flink run -s <dir>/checkpoint_metadata-xxxxx` by explicitly specifying the checkpoint metadata file name 'checkpoint_metadata-xxxxx'. Since metadata file name always changes, it's not easy to programmatically restart a failed Flink job.

What I want is like this: users should be able to start a Flink job by running `flink run -s <dir>` if there's only one checkpointing metadata file in <dir>. If there's none or more than 1 metadata file, the command can fail like it is right now. This way, we can programmatically restart a failed Flink job by hardcoding <dir>)
