Tsuyoshi OZAWA commented on YARN-2517:
--------------------------------------
As Zhijie mentioned, we should have the callback if we need to check errors.
IMHO, if we have a thread for the callback "onError", we should also have
"onEntitiesPut" since the complexity doesn't increase so much and it's useful
to distinguish connection-level exceptions from entity-level errors.

> 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.
