Subject [jira] [Commented] (YARN-6069) CORS support in timeline v2
Date Thu, 16 Feb 2017 13:27:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15869914#comment-15869914

Rohith Sharma K S commented on YARN-6069:
-----------------------------------------

I think folks are forgetting one important thing that this JIRA is only for TimelineReader
v.2 server which uses GET operation only. It is not necessarily required to worry about any
custom configurations that controls other HTTP operations. The assumption of user will use
those configurations does not holds good here. 
And regarding timeline configurations re use, since it is new daemon user can configure using
ATSv2 documentation. Need not to be mandatorily reuse all the configurations as same as ATSv1.
It is new system designed and there will be a couple of changes also expected in  configurations
too.

> 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.
