Hi Raja, Can you tell me the API call that you are trying to issue? If it is not a GET request, it could be that you are suffering from this bug:
https://issues.apache.org/jira/browse/YARN-2031 In my case the tracking url shown on the resource manager ui is indeed one that targets the YARN proxy, i.e., POST/DELETE/PUT requests are not supported. However, the tracking url obtained from the YARN cli directly refers to the jobmanager.
