Examples with HTraceConfiguration org.apache.htrace.core.HTraceConfiguration used on opensource projects

Example 1 with HTraceConfiguration

use of org.apache.htrace.core.HTraceConfiguration in project hadoop by apache.

the class TestTraceUtils method testExtraConfig.

@Test
public void testExtraConfig() {
    String key = "test.extra.config";
    String oldValue = "old value";
    String newValue = "new value";
    Configuration conf = new Configuration();
    conf.set(TEST_PREFIX + key, oldValue);
    LinkedList<ConfigurationPair> extraConfig = new LinkedList<ConfigurationPair>();
    extraConfig.add(new ConfigurationPair(TEST_PREFIX + key, newValue));
    HTraceConfiguration wrapped = TraceUtils.wrapHadoopConf(TEST_PREFIX, conf, extraConfig);
    assertEquals(newValue, wrapped.get(key));
}

Example 2 with HTraceConfiguration

use of org.apache.htrace.core.HTraceConfiguration in project hadoop by apache.

the class TestTraceUtils method testWrappedHadoopConf.

@Test
public void testWrappedHadoopConf() {
    String key = "sampler";
    String value = "ProbabilitySampler";
    Configuration conf = new Configuration();
    conf.set(TEST_PREFIX + key, value);
    HTraceConfiguration wrapped = TraceUtils.wrapHadoopConf(TEST_PREFIX, conf);
    assertEquals(value, wrapped.get(key));
