---------------------------------
Summary: Jobs endpoint returns duplicated jobs
Key: FLINK-20195
URL:
https://issues.apache.org/jira/browse/FLINK-20195 Project: Flink
Issue Type: Bug
Affects Versions: 1.11.2
Reporter: Ingo Bürk
The GET /jobs endpoint can, for a split second, return a duplicated job after it has been cancelled. This occurred in Ververica Platform after canceling a job (using PATCH /jobs/\{jobId}) and calling GET /jobs.
I've reproduced this and queried the endpoint in a relatively tight loop (~ every 0.5s) to log the responses of GET /jobs and got this:
{code:java}
…
{"jobs":[{"id":"e110531c08dd4e3dbbfcf7afc1629c3d","status":"RUNNING"},{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELLING"}]}
{"jobs":[{"id":"e110531c08dd4e3dbbfcf7afc1629c3d","status":"RUNNING"},{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELLING"}]}
{"jobs":[{"id":"e110531c08dd4e3dbbfcf7afc1629c3d","status":"FAILED"},{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELED"},{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELED"}]}
{"jobs":[{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELED"},{"id":"e110531c08dd4e3dbbfcf7afc1629c3d","status":"FAILED"}]}
{"jobs":[{"id":"53fd11db25394308862c997dce9ef990","status":"CANCELED"},{"id":"e110531c08dd4e3dbbfcf7afc1629c3d","status":"FAILED"}]}
…{code}
You can see in in between that for just a moment, the endpoint returned the same Job ID twice.
