Subject [jira] [Commented] (YARN-3047) [Data Serving] Set up ATS reader with basic request serving structure and lifecycle
Date Wed, 08 Jul 2015 06:43:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14618074#comment-14618074

Varun Saxena commented on YARN-3047:

bq. Can't we just reuse the existing config "timeline_service_webapp" instead of creating
a new? In fact, user is bind of writer. They just know timeline_service_webapp is where they
can access the data.
What if writer and reader are on same machine ? That's why I segregated it. 
Didn't get second part of your statement. If timeline_service_webapp address is known to user
and that is used for writer, how will they reach reader ? Either port or IP should be different
for reader.

bq. Please let me know if I've missed something: the new configuration name is and the old
configuration default value are used together
Looks like a typo. Should be changed

> Per design in YARN-2938, set up the ATS reader as a service and implement the basic structure
as a service. It includes lifecycle management, request serving, and so on.
