Subject [jira] [Commented] (YARN-2517) Implement TimelineClientAsync
Date Tue, 25 Nov 2014 23:52:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14225420#comment-14225420

Sangjin Lee commented on YARN-2517:
-----------------------------------

Thanks for the clarification [~zjshen].

If there is a data integrity issue and the client receives an error due to such a data integrity
problem, I wonder what it can do upon receiving it. Can you talk about possible non-trivial
action here? To me, it seems like what it can do is really limited.

> 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.
