@Test
public void testOpencensusJaeger() {
 // 1. configure the jaeger exporter

 // 2. Configure 100% sample rate, otherwise, few traces will be sampled.
 TraceConfig traceConfig = Tracing.getTraceConfig();
 TraceParams activeTraceParams = traceConfig.getActiveTraceParams();
 traceConfig.updateActiveTraceParams(
   activeTraceParams.toBuilder().setSampler(Samplers.alwaysSample()).build());
 // 3. Get the global singleton Tracer object.
 Tracer tracer = Tracing.getTracer();
 // 4. Create a scoped span, a scoped span will automatically end when closed.
 // It implements AutoClosable, so it'll be closed when the try block ends.
 try (Scope scope = tracer.spanBuilder("query").startScopedSpan()) {
  runTransactions();
 }
 // 5. Gracefully shutdown the exporter, so that it'll flush queued traces to Jaeger.
 Tracing.getExportComponent().shutdown();
