All Implemented Interfaces:

AutoCloseable, ClientHighAvailabilityServices, HighAvailabilityServices

public class StandaloneHaServices
extends AbstractNonHaServices

An implementation of the HighAvailabilityServices for the non-high-availability case. This implementation can be used for testing, and for cluster setups that do not tolerate failures of the master processes (JobManager, ResourceManager).

This implementation has no dependencies on any external services. It returns a fix pre-configured ResourceManager and JobManager, and stores checkpoints and metadata simply on the heap or on a local file system and therefore in a storage without guarantees.
