[jira] [Comment Edited] (YARN-6069) CORS support in timeline v2
[ https://issues.apache.org/jira/browse/YARN-6069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15869094#comment-15869094 ]

-------------------------------------------------------------
As of now for timeline service, we use the timeline specific configurations if they are configured and fall back to common configurations in HttpCrossOriginFilterInitializer, if not configured.
Now for ATSv2 we can potentially use common configurations itself. As ATSv2 is new, we can probably define it this way.
However this does not give us flexibility of switching off CORS for some modules and not for some(if same configuration is used). But I wonder why someone would be doing it i.e. switch off CORS for some and not switch it off for other.

> By default the browser prevents accessing resources from multiple domains. In most cases the UIs would be loaded form a domain different from that of timeline server. Hence without CORS support, it would be difficult for the UIs to load data from timeline v2.
> YARN-2277 must provide more info on the implementation.
