Subject [jira] [Commented] (YARN-6069) CORS support in timeline v2
Date Thu, 16 Feb 2017 03:50:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15869094#comment-15869094
] 

Varun Saxena commented on YARN-6069:
------------------------------------

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.

> 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.
