Yarn Fair Scheduler Allocation file not found in CDH 5.8.2

[#1]

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
