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 and manual fine tuning after the migration.

In CDP, Capacity Scheduler is the default and supported scheduler. You have to transition from Fair Scheduler to Capacity Scheduler before migrating 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.
  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.
