Yarn Fair Scheduler Allocation file not found in CDH 5.8.2

Hi Everyone,

We have been trying to use Yarn SLS outside of our cluster to verify our fair scheduler configuration. So i tried to run SLS with the exact same pools configuration set in our prodcution cluster. Does anyone know where do the Manager save the configured pools ( CM > Yarn > Ressource Pools Configuration) ? Is there a file named fair-scheduler.xml sotred ?

PS : there is no "fair-scheduler.xml" file in my AM node.

Thank you.

In CM you can retrieve the file that is pushed out from the RM instance information page.

Go to the Yarn service -> Instances (in the bar on top) -> Select a RM instance from the list on the right -> Process (in the top bar again). There should be a list of all the configuration and environment files there that you can download.

If they do not show up click the Show link under Configuration Files/Environment.

Hope that helps,

Wilfred
