Example 6 with HierarchyCircuitBreakerService

use of org.elasticsearch.indices.breaker.HierarchyCircuitBreakerService in project elasticsearch by elastic.

the class RestControllerTests method setup.

@Before
public void setup() {
    Settings settings = Settings.EMPTY;
    circuitBreakerService = new HierarchyCircuitBreakerService(Settings.builder().put(HierarchyCircuitBreakerService.IN_FLIGHT_REQUESTS_CIRCUIT_BREAKER_LIMIT_SETTING.getKey(), BREAKER_LIMIT).build(), new ClusterSettings(Settings.EMPTY, ClusterSettings.BUILT_IN_CLUSTER_SETTINGS));
    // we can do this here only because we know that we don't adjust breaker settings dynamically in the test
    inFlightRequestsBreaker = circuitBreakerService.getBreaker(CircuitBreaker.IN_FLIGHT_REQUESTS);
    HttpServerTransport httpServerTransport = new TestHttpServerTransport();
    restController = new RestController(settings, Collections.emptySet(), null, null, circuitBreakerService);
