Review Comment:
@1996fanrui Thanks for the quick feedback, I have added the background. I
also add a example here.
For FINISHED job `6f4257aaf163d19a6fa1519479795c11`:
1. when request `GET /jobs/:jobid` -> `GET
/jobs/6f4257aaf163d19a6fa1519479795c11`, the response is:
```json
{
"jid": "6f4257aaf163d19a6fa1519479795c11",
"name": "app442315instance1204699",

"state": "FINISHED",
"start-time": 1754445330065,
"end-time": 1754445366256,
"duration": 36191,
"maxParallelism": -1,

"timestamps": {

"FAILED": 0,
"CANCELLING": 0,
"FAILING": 0,
"RESTARTING": 0,
"SUSPENDED": 0
},
......
}
```
2. when request `GET /jobs/:jobid/checkpoints` -> `GET
/jobs/6f4257aaf163d19a6fa1519479795c11/checkpoints`, the response is:
```json
{
"errors": [
"org.apache.flink.runtime.rest.NotFoundException: Job
6f4257aaf163d19a6fa1519479795c11 not found\n\tat
org.apache.flink.runtime.rest.handler.job.checkpoints.AbstractCheckpointStatsHandler.lambda$handleRequest$2(AbstractCheckpointStatsHandler.java:102)\n\tat
java.util.concurrent.CompletableFuture.uniExceptionally(CompletableFuture.java:884)\n\tat
java.util.concurrent.CompletableFuture$UniExceptionally.tryFire(CompletableFuture.java:866)\n\tat
..."
}
```
Maybe the current solution catching the exception in `getLastCheckpoint()`
is somewhat unintuitive here. Another solution is catching the exception `Job
not found` in `observeLatestCheckpoint()`
```Java
private void observeLatestCheckpoint(FlinkResourceContext<CR> ctx, String
jobId) {
var status = ctx.getResource().getStatus();
var jobStatus = status.getJobStatus();
ctx.getFlinkService()
.getLastCheckpoint(JobID.fromHexString(jobId),
ctx.getObserveConfig())
.ifPresentOrElse(
snapshot ->
jobStatus.setUpgradeSavepointPath(snapshot.getLocation()),
() -> {
if (ReconciliationUtils.isJobCancelled(status)) {
// For cancelled jobs the observed savepoint
is always definite,
// so if empty we know the job doesn't have
any
// checkpoints/savepoints
jobStatus.setUpgradeSavepointPath(null);
}
});
}
```
And can check the job is FINISHED by
```Java
JobStatus.FINISHED == resource.getStatus().getJobStatus().getState();
```
Do you have any suggestions?
