Examples of org.apache.hadoop.metrics.spi.NoEmitMetricsContext

org.apache.hadoop.metrics.spi.NoEmitMetricsContext
A MetricsContext that does not emit data, but, unlike NullContextWithUpdate, does save it for retrieval with getAllRecords(). This is useful if you want to support {@link MetricsServlet}, but not emit metrics in any other way.

  /**
   * Initializes, for testing, two NoEmitMetricsContext's, and adds one value 
   * to the first of them.

  public void setUp() throws IOException {
    nc1 = new NoEmitMetricsContext();
    nc1.init("test1", ContextFactory.getFactory());
    nc2 = new NoEmitMetricsContext();
    nc2.init("test2", ContextFactory.getFactory());
    contexts = new ArrayList<MetricsContext>();
    contexts.add(nc1);
    contexts.add(nc2);
