Sangjin Lee updated YARN-3030:
------------------------------
Attachment: YARN-3030.001.patch
Posted patch v.1.
(1)
It sets up the basic skeleton of the aggregator service hierarchy.
BaseAggregatorService sets up a core aggregator service.
AppLevelAggregatorService is an extension that is instantiated per app.
(2)
I added a partial implementation of the PerNodeAggregator. It serves as a REST
end point, and provides lifecycle methods so per-app in-memory aggregators can
be created and destroyed according to the app lifecycle.
(3)
Added a few unit tests, and cleaned up the pom a little bit.
This is still a skeleton. I simply used the existing common APIs from ATS to
fill in the arguments and so on. We'll need to add more as our APIs jell.
> set up ATS writer with basic request serving structure and lifecycle

> Also, as part of this JIRA, we should come up with the ATS client API for
