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.
> CORS support in timeline v2

> 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.
