[jira] [Created] (YARN-3067) REST API for System Configuration

Doug Haigh created YARN-3067:
--------------------------------

             Summary: REST API for System Configuration
                 Key: YARN-3067
                 URL: https://issues.apache.org/jira/browse/YARN-3067
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: api, client
    Affects Versions: 2.6.0
         Environment: REST API
            Reporter: Doug Haigh


While the name node exposes its configuration via <nn_host>:<nn_port>/conf and resource manager exposes its configuration via <rm_host>:<rm_port>/conf, neither provide a complete picture of the system's configuration for applications that use the YARN REST API.

This JIRA is to request a REST API to get all services' configuration information whether it is stored in the resource manager or something external like zookeeper. Essentially this would return information similar to what <nn>/conf and <rm>/conf return, but be guaranteed to have all information so that a REST API user would not require Hadoop configuration files to know how services are setup.
