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.
