Subject [jira] [Commented] (YARN-6069) CORS support in timeline v2
Date Thu, 16 Feb 2017 14:35:41 GMT

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

bq. 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. 
Sorry didn't get you. Other than allowed methods configuration, which CORS related configuration
is not relevant here.
Also any idea what purpose max age serves. We do not make any check in the filter based on
it.

> 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.
