 [RM HA] Rest api endpoints doing redirect incorrectly
 -

 Key: YARN-2605
 URL: https://issues.apache.org/jira/browse/YARN-2605
 Project: Hadoop YARN
  Issue Type: Sub-task
  Components: resourcemanager
Affects Versions: 2.4.0
Reporter: bc Wong
Assignee: Xuan Gong
  Labels: newbie
 Attachments: YARN-2605.1.patch


 The standby RM's webui tries to do a redirect via meta-refresh. That is fine 
 for pages designed to be viewed by web browsers. But the API endpoints 
 shouldn't do that. Most programmatic HTTP clients do not do meta-refresh. I'd 
 suggest HTTP 303, or return a well-defined error message (json or xml) 
 stating that the standby status and a link to the active RM.
 The standby RM is returning this today:
 {noformat}

 This is standby RM. Redirecting to the current active RM:
