Fair Scheduler to Capacity Scheduler migration

You must migrate from Fair Scheduler to Capacity Scheduler when migrating your cluster to CDP. The migration process involves automatically converting certain Fair Scheduler configuration to Capacity Scheduler configuration prior to the upgrade and manual fine tuning after the upgrade.

In CDP, Capacity Scheduler is the default and supported scheduler. You have to transition from Fair Scheduler to Capacity Scheduler before upgrading from CDH to CDP Private Cloud Base.

The scheduler transition process includes migrating the YARN settings from Fair Scheduler to Capacity Scheduler:
  1. Pre-migration: Use the fs2cs conversion utility to automatically convert Fair Scheduler into Capacity Scheduler as a part of the Upgrade Wizard in Cloudera Manager.
  2. Migrate all of your data to CDP.
  3. Post-migration: Manually configure and fine-tune the scheduler after you migrated all of your data.
