------------------------------------
[~epayne], this design is a inner yarn level to organize different jobs. And it
can unit different platform submitting jobs to yarn.
> [Umbrella] Job group management

> Key: YARN-10431
> URL: https://issues.apache.org/jira/browse/YARN-10431
> Project: Hadoop YARN
> Issue Type: New Feature
> Affects Versions: 2.9.2
> Reporter: jialei weng
> Priority: Major
> Attachments: YarnJobGroupImpl design.pdf
>
>
> In current yarn job management, we don't have an efficient mechanism to
> manage several jobs together. For example, one batch job may trigger several
> sub-jobs to running at the same time, like one job to process the data and
> another one monitor job metrics. And when we want to cancel these jobs, we
> have to kill them one by one in current design. I proposal a job group
> concept to handle such parent-child jobs as one unit.
