Subject [jira] [Commented] (YARN-4009) CORS support for ResourceManager REST API
Date Sat, 03 Oct 2015 14:48:27 GMT

    [ https://issues.apache.org/jira/browse/YARN-4009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14942336#comment-14942336
] 

Jonathan Eagles commented on YARN-4009:
---------------------------------------

+1. I have tried this patch out and reviewed the code. Minor nits 
* Configuration usage set(_config setting_, 'true") is better as setBoolean(_config setting_,
true)
* timeline server now uses its own different way to enable. So if i turn on resource manager
and timeline server both on but nothing else, I get a CORS disabled message in the timeline
server log even though it is enabled. Could you file a jira to address this spurious log message?

> Currently the REST API's do not have CORS support. This means any UI (running in browser)
cannot consume the REST API's. For ex Tez UI would like to use the REST API for getting application,
application attempt information exposed by the API's. 
> It would be very useful if CORS is enabled for the REST API's.
