@Haosdent, sorry for delay; i’m not familiar with scala, the compilation takes
me some time. you are right, after changing the file you told me, it works. But
that’s not what i want, it my situation, marathon should takes both reserved
resource and unreserved resource; when using official marathon version,
marathon will use static reserved resources (mesos agent started with
`--default_role dev` flag, and marathon with `--mesos_role dev`), but it seems
marathon did not take static reserved resource as *reserved resource*,
```
Considering unreserved resources with roles {dev}. Not all basic resources
satisfied: cpus NOT SATISFIED (1.0 > 0.0), mem NOT SATISFIED (128.0 > 0.0)
(mesosphere.mesos.ResourceMatcher$:marathon-akka.actor.default-dispatcher-6)
```
the above shows that marathon only considers *unreserved* resources with role
`dev`. However IMO, all resources with role `dev` should be reserved resources,
right? i’m quite confused, @haosdent, are resources provided by mesos agent
that started with `--default_role dev` flag unreseved resources? i will advise
mesosphere/marathon community for more help.
Thanks,
