Bowen Li created FLINK-7566:
-------------------------------
Summary: if there's only one checkpointing metadata file in <dir>,
`flink run -s <dir>` should resume from that metadata file
Key: FLINK-7566
URL: https://issues.apache.org/jira/browse/FLINK-7566
Project: Flink
Issue Type: Improvement
Components: Startup Shell Scripts
Affects Versions: 1.3.2
Environment: 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>
