Subject Re: Total resources available versus actually available
Date Mon, 09 Feb 2015 19:24:40 GMT
Mesos doesn't know anything about non-Mesos processes running on the
machine consuming resources. So yes, Mesos would still offer the resources
and allow a task to be placed there. The assumption is that all of the
resources specified via --resources are available for Mesos to allocate.
