Weiwei Yang commented on YARN-8559:
-----------------------------------
Thanks [~leftnoteasy], that's correct. "scheduler-conf" right now is a PUT for
refreshing CS configs. There is "http://RM_ADDR/scheduler"; to retrieve
scheduler info, see more at [apache
doc|http://hadoop.apache.org/docs/r3.1.0/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Scheduler_API].
It dumps scheduler info but not directly from conf. I am thinking since we
support the mutable configuration via REST (scheduler-conf), we should support
GET too. Thoughts [~leftnoteasy], [~banditka]?
Let me reopen this JIRA for more discussion then.
Thanks
> Expose scheduling configuration info in Resource Manager's /conf endpoint

> Key: YARN-8559
> URL: https://issues.apache.org/jira/browse/YARN-8559
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Reporter: Anna Savarin
> Priority: Minor
>
> 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.
