[jira] [Commented] (YARN-8559) Expose mutable-conf scheduler's
configuration in RM /scheduler-conf endpoint
[ https://issues.apache.org/jira/browse/YARN-8559?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16564662#comment-16564662 ]

-----------------------------------
Hi [~suma.shivaprasad]/[~leftnoteasy]
Thanks for the comments.
bq. Can you pls add documentation in ResourceManagerRest.md
Sure, will update in next patch.
bq. can we use the existing logic similar to ConfServlet?
I think we should stick to the JAX-RS pattern in RMWebService, that is more consistent. Also it is easier to support both standard json/xml content type without parsing the request. After all DAO is just a wrapper, non-functional change.
bq. it might be better to protect access of the REST endpoint by admin
Make sense to me, will update in next patch.
Thanks

> All Hadoop services provide a set of common endpoints (/stacks, /logLevel, /metrics, /jmx, /conf). In the case of the Resource Manager, part of the configuration comes from the scheduler being used. Currently, these configuration key/values are not exposed through the /conf endpoint, thereby revealing an incomplete configuration picture.
> Make an improvement and expose the scheduling configuration info through the RM's /conf endpoint.
