YARN Fair Scheduler to Capacity Scheduler Sidecar migration from CDH to CDP
The YARN Fair Scheduler is not supported in CDP. You must migrate to use the Capacity Scheduler.
Cloudera provides a tool to convert the Fair Scheduler into a Capacity Scheduler configuration. However, the features of Capacity Scheduler are not the same as the features of Fair Scheduler. Hence, the conversion utility cannot convert every Fair Scheduler configuration into a Capacity Scheduler configuration. After the automatic conversion and once the migration is completed, you must manually tune the scheduler configurations to ensure that the resulting scheduling configuration fits your organization’s internal goals and SLAs.
For a complete description of the process, and to learn more about the differences between Fair Scheduler and Capacity Scheduler, see Fair Scheduler to Capacity Scheduler migration overview

fs2cs), see Converting Fair Scheduler to Capacity
