Varun Saxena created YARN-6159:
----------------------------------

             Summary: In timeline v2 documentation, the code snippet given for 
creating timeline client has a mistake
                 Key: YARN-6159
                 URL: https://issues.apache.org/jira/browse/YARN-6159
             Project: Hadoop YARN
          Issue Type: Bug
          Components: documentation
            Reporter: Varun Saxena
            Priority: Trivial


In TimelineServiceV2.md, under section Publishing application specific data, we 
have the following code snippet. Here, 
{{timelineClient.putEntitiesAsync(entity);}} should be 
{{client.putEntitiesAsync(entity);}} instead.
{code}
    // Create and start the Timeline client v.2
    TimelineClient client = TimelineClient.createTimelineClient(appId);
    client.init(conf);
    client.start();

    try {
      TimelineEntity myEntity = new TimelineEntity();
      myEntity.setEntityType("MY_APPLICATION");
      myEntity.setEntityId("MyApp1")
      // Compose other entity info

      // Blocking write
      client.putEntities(entity);

      TimelineEntity myEntity2 = new TimelineEntity();
      // Compose other info

      // Non-blocking write
      timelineClient.putEntitiesAsync(entity);

    } catch (IOException e) {
      // Handle the exception
    } catch (RuntimeException e) {
{code}
Below can also be changed to client to keep it consistent.
{code}
    amRMClient.registerTimelineClient(timelineClient)Íž
{code}
