[jira] [Created] (FLINK-10520) Job save points REST API fails unless parameters are specified

----------------------------------

             Summary: Job save points REST API fails unless parameters are specified
                 Key: FLINK-10520
                 URL: https://issues.apache.org/jira/browse/FLINK-10520
             Project: Flink
          Issue Type: Bug
          Components: REST
    Affects Versions: 1.6.1
            Reporter: Elias Levy


The new REST API POST endpoint, {{/jobs/:jobid/savepoints}}, returns an error unless the request includes a body with all parameters ({{target-directory}} and {{cancel-job}})), even thought the [documentation|https://ci.apache.org/projects/flink/flink-docs-master/api/java/org/apache/flink/runtime/rest/handler/job/savepoints/SavepointHandlers.html] suggests these are optional.

If a POST request with no data is made, the response is a 400 status code with the error message "Bad request received."

If the POST request submits an empty JSON object ( {} ), the response is a 400 status code with the error message "Request did not match expected format SavepointTriggerRequestBody."  The same is true if only the {{target-directory}} or {{cancel-job}} parameters are included.

As the system is configured with a default savepoint location, there shouldn't be a need to include the parameter in the quest.
