Example 86 with BlockingQueue

use of java.util.concurrent.BlockingQueue in project jstorm by alibaba.

the class SaslTransportPlugin method getServer.

@Override
public TServer getServer(TProcessor processor) throws IOException, TTransportException {
    int port = type.getPort(storm_conf);
    TTransportFactory serverTransportFactory = getServerTransportFactory();
    TServerSocket serverTransport = new TServerSocket(port);
    int numWorkerThreads = type.getNumThreads(storm_conf);
    Integer queueSize = type.getQueueSize(storm_conf);
    TThreadPoolServer.Args server_args = new TThreadPoolServer.Args(serverTransport).processor(new TUGIWrapProcessor(processor)).minWorkerThreads(numWorkerThreads).maxWorkerThreads(numWorkerThreads).protocolFactory(new TBinaryProtocol.Factory(false, true));
    if (serverTransportFactory != null) {
        server_args.transportFactory(serverTransportFactory);
    }
    BlockingQueue workQueue = new SynchronousQueue();
    if (queueSize != null) {
        workQueue = new ArrayBlockingQueue(queueSize);
    }
    ThreadPoolExecutor executorService = new ExtendedThreadPoolExecutor(numWorkerThreads, numWorkerThreads, 60, TimeUnit.SECONDS, workQueue);
    server_args.executorService(executorService);
    return new TThreadPoolServer(server_args);
}

Example 87 with BlockingQueue

use of java.util.concurrent.BlockingQueue in project HugeCollections-OLD by peter-lawrey.

Example 88 with BlockingQueue

use of java.util.concurrent.BlockingQueue in project HugeCollections-OLD by peter-lawrey.

the class SharedJSR166TestCase method testTimedPoll0.

/**
     * timed poll with zero timeout succeeds when non-empty, else times out
     */

    }
    assertNull(q.poll(0, MILLISECONDS));
    checkEmpty(q);
}

Example 89 with BlockingQueue

use of java.util.concurrent.BlockingQueue in project HugeCollections-OLD by peter-lawrey.

the class SharedJSR166TestCase method testRemove.

/**
     * remove removes next element, or throws NSEE if empty
     */
@Test
public void testRemove() throws IOException {
    BlockingQueue q = populatedQueue(SIZE);
    for (int i = 0; i < SIZE; ++i) {

Example 90 with BlockingQueue

use of java.util.concurrent.BlockingQueue in project HugeCollections-OLD by peter-lawrey.
