Subject [jira] [Updated] (YARN-2928) YARN Timeline Service v.2: alpha 1
Date Mon, 18 Jul 2016 19:20:21 GMT

     [ https://issues.apache.org/jira/browse/YARN-2928?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sangjin Lee updated YARN-2928:
------------------------------
    Release Note: 
We introduce an early preview (alpha 1) of a major revision of YARN Timeline Service: v.2.
YARN Timeline Service v.2 addresses two major challenges: improving scalability and reliability
of Timeline Service, and enhancing usability by introducing flows and aggregation.

YARN Timeline Service v.2 alpha 1 is provided so that users and developers can test it and
provide feedback and suggestions for making it a ready replacement for Timeline Service v.1.x.
It should be used only in a test capacity. Most importantly, security is not enabled. Do not
set up or use Timeline Service v.2 until security is implemented if security is a critical
requirement.

More details are available in the [YARN Timeline Service v.2](./hadoop-yarn/hadoop-yarn-site/TimelineServiceV2.html)
documentation.

I added the release notes contents mostly along the lines of other major features in the release
notes. I kept it brief since most of the details are available in the main documentation.

[~andrew.wang], could you double check the hyperlink there to ensure it is correct? That's
how it's referenced in the main site html, but I just want to make sure that's correct.

> We have the application timeline server implemented in yarn per YARN-1530 and YARN-321.
Although it is a great feature, we have recognized several critical issues and features that
need to be addressed.
> This JIRA proposes the design and implementation changes to address those. This is phase
1 of this effort.
