Subject [jira] [Updated] (YARN-3030) set up ATS writer with basic request serving structure and lifecycle
Date Tue, 27 Jan 2015 01:39:35 GMT

Sangjin Lee updated YARN-3030:
    Attachment: YARN-3030.004.patch

Posted patch v.4 to address Zhijie's suggestions.

By adding the per-node aggregator web service directly to the node manager web app we're able
to get around YARN-3087, but it required adding a dependency from node manager to timeline
service (yuck).

Also it was bit involved because we need to make sure we still retain the aux service behavior
(to be able to leverage the aux service lifecycle) and make sure the same app-level service
manager is shared between the aux service and the web service.

Verified by adding it as an aux-service of the node manager.

> Per design in YARN-2928, create an ATS writer as a service, and implement the basic service
structure including the lifecycle management.
> Also, as part of this JIRA, we should come up with the ATS client API for sending requests
to this ATS writer.
