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

             Summary: make Flink Web Backend a little bit more restful
                 Key: FLINK-5848
                 URL: https://issues.apache.org/jira/browse/FLINK-5848
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
    Affects Versions: 1.1.4, 1.2.0
            Reporter: Fabian Wollert


we are using the web backend for managing flink jobs (cancelling, starting, etc.). Unfortunately the Backend is not completely RESTful, the responses are mixed.

E.g. https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/ClusterOverviewHandler.java is showing that if a error occurs in the backend, its not resulting in a HTTP error code and the response is not JSON.
