Examples with EventQueue org.apache.oozie.event.EventQueue used on opensource projects

Example 1 with EventQueue

use of org.apache.oozie.event.EventQueue in project oozie by apache.

the class EventHandlerService method init.

@Override
public void init(Services services) throws ServiceException {
    try {
        Configuration conf = services.getConf();
        LOG = XLog.getLog(getClass());
        Class<? extends EventQueue> queueImpl = (Class<? extends EventQueue>) ConfigurationService.getClass(conf, CONF_EVENT_QUEUE);
        eventQueue = queueImpl == null ? new MemoryEventQueue() : (EventQueue) queueImpl.newInstance();
        eventQueue.init(conf);
        // initialize app-types to switch on events for
        initApptypes(conf);
        // initialize event listeners
        initEventListeners(conf);
        // initialize worker threads via Scheduler
        initWorkerThreads(conf, services);
        eventsEnabled = true;
        LOG.info("EventHandlerService initialized. Event queue = [{0}], Event listeners configured = [{1}]," + " Events configured for App-types = [{2}], Num Worker Threads = [{3}]", eventQueue.getClass().getName(), listenerMap.toString(), apptypes, numWorkers);
    } catch (Exception ex) {
        throw new ServiceException(ErrorCode.E0100, ex.getMessage(), ex);
