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

             Summary: Job Cancel button doesn't work on Yarn
                 Key: FLINK-2989
                 URL: https://issues.apache.org/jira/browse/FLINK-2989
             Project: Flink
          Issue Type: Bug
          Components: Webfrontend
            Reporter: Sachin Goel


The newly added Cancel button doesn't work on Yarn, when accessing via Yarn Web Application proxy. It works fine when we're directly on the web monitor.
The reason is Yarn doesn't allow DELETE requests to the AM yet. It should be enabled in 2.8.0. [YARN-2031, YARN-2084.]
A workaround for now can be to use a {{GET}} method instead of {{DELETE}}, but that breaks the conventions of REST.
