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.
