haosdent reassigned MESOS-5911: ------------------------------- Assignee: haosdent > Webui redirection to leader in browser does not work > ---------------------------------------------------- > > Key: MESOS-5911 > URL: https://issues.apache.org/jira/browse/MESOS-5911 > Project: Mesos > Issue Type: Bug > Affects Versions: 1.0.0 > Reporter: Jacob Janco > Assignee: haosdent > Priority: Blocker > Labels: webui > > We deployed 1.0.0-rc4 in a small test cluster with 3 masters/5 agents. > Redirection to master curling for state.json returned the expected 307, > however, in browser (chrome/safari/firefox), redirection failed with: > {code} > XMLHttpRequest cannot load <master_url_1>:5050/master/state. No > 'Access-Control-Allow-Origin' header is present on the requested resource. > Origin '<master_url_2>:5050' is therefore not allowed access. > {code} > This is the patch that introduced the redirect on /state (and HTTP calls): > https://reviews.apache.org/r/34646 > The issue is that before this change, the server side does not redirect, the > web UI controller.js decides from the content of the state.json which leader > to redirect and then invoke redirection itself. Browsers allow this but not > the server side initiated redirect without 'Access-Control-Allow-Origin' > header? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
