Examples with Service org.apache.hadoop.service.Service used on opensource projects

Example 1 with Service

use of org.apache.hadoop.service.Service in project hadoop by apache.

the class TestServiceLifecycle method testStartInInitService.

@Test
public void testStartInInitService() throws Throwable {
    Service service = new StartInInitService();
    BreakableStateChangeListener listener = new BreakableStateChangeListener();
    service.registerServiceListener(listener);
    service.init(new Configuration());
    assertServiceInState(service, Service.STATE.STARTED);
    assertEventCount(listener, 1);
}

Example 2 with Service

use of org.apache.hadoop.service.Service in project hadoop by apache.

the class ResourceManager method resetDispatcher.

private void resetDispatcher() {
    Dispatcher dispatcher = setupDispatcher();
    ((Service) dispatcher).init(this.conf);
    ((Service) dispatcher).start();
    removeService((Service) rmDispatcher);
    // Need to stop previous rmDispatcher before assigning new dispatcher
    // otherwise causes "AsyncDispatcher event handler" thread leak
    ((Service) rmDispatcher).stop();
    rmDispatcher = dispatcher;
    addIfService(rmDispatcher);
    rmContext.setDispatcher(rmDispatcher);
}

Example 3 with Service
