Zhijie Shen commented on YARN-2517:

bq. Clearly, async calls need call-back handlers just for errors. As of today, 
there are no APIs that really need to send back results (not error) 

I realize that another requirement of TimelineClient is to wrap the read APIs 
to facilitate the java app developers. These APIs are going to return results.

> In some scenarios, we'd like to put timeline entities in another thread no to 
> block the current one.
> It's good to have a TimelineClientAsync like AMRMClientAsync and 
> NMClientAsync. It can buffer entities, put them in a separate thread, and 
> have callback to handle the responses.
