Subject [jira] [Created] (YARN-7640) Retrospect to enable CORS related configs by default in YARN
Date Tue, 12 Dec 2017 09:47:00 GMT
Sunil G created YARN-7640:

             Summary: Retrospect to enable CORS related configs by default in YARN
                 Key: YARN-7640
                 URL: https://issues.apache.org/jira/browse/YARN-7640
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager, resourcemanager
    Affects Versions: 3.0.0-beta1
            Reporter: Sunil G

Currently admin has to do below config changes to enable CORS in YARN.

1. Add org.apache.hadoop.security.HttpCrossOriginFilterInitializer to hadoop.http.filter.initializers
2. Set hadoop.http.cross-origin.enabled to true
3. Set hadoop.http.cross-origin.allowed-methods to GET,HEAD
4. Set yarn.nodemanager.webapp.cross-origin.enabled to true 
5. Set yarn.resourcemanager.webapp.cross-origin.enabled to true

For better handling, we could enable this config by default in YARN.
