- QUOTE: As previously described, ResourceManager (RM) is the master that arbitrates all the available cluster resources and thus helps manage the distributed applications running on the YARN system. It works together with the per-node NodeManagers (NMs) and the per-application ApplicationMasters (AMs).
- NodeManagers take instructions from the ResourceManager and manage resources available on a single node.
- ApplicationMasters are responsible for negotiating resources with the ResourceManager and for working with the NodeManagers to start the containers.
