Example 21 with MetricsSystem

use of org.apache.hadoop.metrics2.MetricsSystem in project hadoop by apache.

the class TestQueueMetrics method testMetricsCache.

@Test
public void testMetricsCache() {
    MetricsSystem ms = new MetricsSystemImpl("cache");
    ms.start();
    try {
        String p1 = "root1";
        String leafQueueName = "root1.leaf";
        QueueMetrics p1Metrics = QueueMetrics.forQueue(ms, p1, null, true, conf);
        Queue parentQueue1 = make(stub(Queue.class).returning(p1Metrics).from.getMetrics());
        QueueMetrics metrics = QueueMetrics.forQueue(ms, leafQueueName, parentQueue1, true, conf);
        Assert.assertNotNull("QueueMetrics for A shoudn't be null", metrics);
        // Re-register to check for cache hit, shouldn't blow up metrics-system...
        // also, verify parent-metrics
        QueueMetrics alterMetrics = QueueMetrics.forQueue(ms, leafQueueName, parentQueue1, true, conf);
        Assert.assertNotNull("QueueMetrics for alterMetrics shoudn't be null", alterMetrics);
    } finally {
        ms.shutdown();
    }
