Subject [jira] [Commented] (YARN-6069) CORS support in timeline v2
Date Mon, 20 Feb 2017 18:57:44 GMT

    [ https://issues.apache.org/jira/browse/YARN-6069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15874951#comment-15874951
] 

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

In comment above, I think we can simplify the sentence I wrote above from "Please note that
for timeline service, configuration property, yarn.timeline-service.http-cross-origin.enabled,
if set to true, overrides configuration property hadoop.http.cross-origin.enabled"
 to
"Please note that yarn.timeline-service.http-cross-origin.enabled, if set to true, overrides
hadoop.http.cross-origin.enabled"

> 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.
