Manoj Samel commented on YARN-4692:
-----------------------------------
Hi [~kasha] and team,
I would like to add another type of service to your list, that we are deploying
using Apache slider. I am using slider terminology to explain current use case.
The service is a multi-tenant long running service. Imagine e.g. query service
for large number of users. The application is deployed as one "slider cluster".
For each tenant, we start a component using slider (i.e. a separate Yarn
container). Key service requirements ...
1. Start each container (slider component) as tenant user - not a common user.
2. Large number of containers (hundreds to thousands - one per end user) to be
managed by one AM (as slider stands).
For more details of of use case, see

> YARN-896 focused on getting the ball rolling on the support for services
> (long running applications) on YARN.
> I’d like propose the next stage of this effort: _Simplified and first-class
> support for services in YARN_.
> The chief rationale for filing a separate new JIRA is threefold:
> - Do a fresh survey of all the things that are already implemented in the
> project
> - Weave a comprehensive story around what we further need and attempt to
> rally the community around a concrete end-goal, and
> - Additionally focus on functionality that YARN-896 and friends left for
> higher layers to take care of and see how much of that is better integrated
> into the YARN platform itself.
