Manual configuration of scheduler properties
After upgrading to CDP Private Cloud Base, you must manually 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
yarn-site.xml output files generated by the fs2cs
conversion utility. For information about the Fair Scheduler properties that are
auto-converted by the fs2csconversion utility, see Auto-converted
Fair Scheduler properties.
