----------------------------------
Summary: Improve error message when cancelling job in state
canceled via REST API
Key: FLINK-9389
URL: https://issues.apache.org/jira/browse/FLINK-9389
Project: Flink
Issue Type: Improvement
Components: REST
Affects Versions: 1.5.0
Reporter: Ufuk Celebi
- Request job that has been already cancelled
{code}
$ curl http://localhost:8081/jobs/b577a914ecdf710d4b93a84105dea0c9
{"jid":"b577a914ecdf710d4b93a84105dea0c9","name":"CarTopSpeedWindowingExample","isStoppable":false,"state":"CANCELED",
...omitted...}
{code}
- Cancel job again
{code}
$ curl -XPATCH
http://localhost:8081/jobs/b577a914ecdf710d4b93a84105dea0c9\?mode\=cancel
{"errors":["Job could not be found."]} (HTTP 404)
{code}
Since the actual job resource still exists, I think status code 404 is
confusing. I think a better message should indicate that the job is already in
state CANCELED.
