Wangda Tan commented on YARN-8559:
----------------------------------
Thanks [~cheersyang],
Some suggestions:
1) Instead of creating a new DAO, can we use the existing logic similar to
org.apache.hadoop.conf.ConfServlet?
2) Also, it might be better to protect access of the REST endpoint by admin
only since it includes some sensitive information like ACL, etc. For sensitive
information of scheduler, user can access /scheduler.
> Expose mutable-conf scheduler's configuration in RM /scheduler-conf endpoint

> 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.
