> Submitting a PR to merge the work into https://github.com/mesos/myriad/tree/issue_14 branch.
> The feature currently works as follows
> - Build myriad with a special "zero" profile added to myriad-config-default.yml:
> {code}
> profiles:
>   zero:
>     cpu: 0
>     mem: 0
> {code}
> - Flexup a few NMs using /api/cluster/flexup, but with "zero" profile:
> {code}
> {
>   "instances":3, "profile": "zero"
> }
> {code}
> - Submit a M/R job to the Resource Manager.
> - The MesosUI should show "placeholder" mesos tasks (prefixed with "yarn_") for each yarn container. The job should finish successfully (although the NMs were originally launched with 0 capacities).
