Subject [jira] [Commented] (YARN-2854) The document about timeline service and generic service needs to be updated
Date Mon, 24 Nov 2014 19:27:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14223363#comment-14223363

Zhijie Shen commented on YARN-2854:
-----------------------------------

[~Naganarasimha], thanks of taking this documentation work. I suggest doing the following
updates:

1. If you read through the document, the per-framework data (which is actually the basic timeline
service) and the generic data (aka the generic history service) sound two equal pieces in
this daemon. It may be better to promote the timeline service as the first-class citizen of
this document, and then explain the generic history service as the build-in payload of it.

2. We need to update the current status section. Up till now, the essential functionality
of the timeline server is done, and it can work in both insecure and secure modes. The generic
history service has already ridden on the timeline store. The coming thing may be the scalability
and reliability of the timeline service. As the target fix version is set to 2.7.0. We may
update it around the end of the release.

2. Add a section about enabling security of the timeline server. I can help with this section
if necessary.

3. The configurations about the generic history service needs to be updated.

4. It may be better to enhance the client example code, at least to show how to create a domain,
and put the entity into a particular domain.

5. For the API specifications, let's still keep it separately: YARN-1876
