Arun Suresh commented on YARN-4692:
-----------------------------------
Missed adding this to my previous comment:
# Container Auto-Scaling:
Someway to allow user to specify rules like "Add/Remove Container for role if
*mem*/*iops*/*cpu per container* exceeds/goes below threshold” when launching
an LR App. We can probably design a rule specification that can be consumed by
the service or else we can probably provide Interface hooks that can be
extended/implemented by the end user and packaged with the App.

> 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.
