Manual configuration of scheduler properties

After upgrading to CDP Private Cloud Base, you must manually add the content of the yarn-site.xml output file, and then fine-tune the scheduler configurations using the YARN Queue Manager UI to ensure that the resulting configurations suit your requirements. You can use Cloudera Manager Advanced configuration snippet (Safety Valve) to configure a property that is missing from the YARN Queue Manager UI.

The features of Capacity Scheduler are not exactly the same as the features of Fair Scheduler. Hence, the conversion utility cannot convert every Fair Scheduler configuration into a Capacity Scheduler configuration. Therefore, you must manually tune the scheduler configurations to ensure that the resulting scheduling configuration fits your organization’s internal goals and SLAs after conversion. If needed, further change the scheduler properties in the capacity-scheduler.xml and yarn-site.xml output files generated by the fs2cs conversion utility. For information about the Fair Scheduler properties that are auto-converted by the fs2cs conversion utility, see Auto-converted Fair Scheduler properties.

You can configure the properties manually using the YARN Queue Manager UI. If you see any properties that are unavailable in the Queue Manager UI, you can use Cloudera Manager configuration snippet (Safety Valves) to configure them.
