Examples with FrameworkGroupFactory org.apache.hadoop.mapreduce.counters.CounterGroupFactory.FrameworkGroupFactory used on opensource projects

Example 1 with FrameworkGroupFactory

use of org.apache.hadoop.mapreduce.counters.CounterGroupFactory.FrameworkGroupFactory in project hadoop by apache.

the class GroupFactoryForTest method testTaskCounter.

@SuppressWarnings("rawtypes")
@Test
public void testTaskCounter() {
    GroupFactory groupFactory = new GroupFactoryForTest();
    FrameworkGroupFactory frameworkGroupFactory = groupFactory.newFrameworkGroupFactory(TaskCounter.class);
    Group group = (Group) frameworkGroupFactory.newGroup("TaskCounter");
    FrameworkCounterGroup counterGroup = (FrameworkCounterGroup) group.getUnderlyingGroup();
    org.apache.hadoop.mapreduce.Counter count1 = counterGroup.findCounter(TaskCounter.PHYSICAL_MEMORY_BYTES.toString());
    Assert.assertNotNull(count1);
    count1.increment(10);
    count1.increment(10);
    Assert.assertEquals(20, count1.getValue());
    // Verify no exception get thrown when finding an unknown counter
    org.apache.hadoop.mapreduce.Counter count2 = counterGroup.findCounter(TaskCounter.MAP_PHYSICAL_MEMORY_BYTES_MAX.toString());
    Assert.assertNotNull(count2);
    count2.increment(5);
    count2.increment(10);
    Assert.assertEquals(10, count2.getValue());
}
