Michael Park commented on MESOS-2137:
-------------------------------------
The following are the 3 valid states of a Resource protobuf message that
represents 2 cpus.
{code:title=1. unreserved}
message Resource {
name: "cpus",
value: 2,
role: "*",
reservation: STATIC
}
{code}
{code:title=2. statically reserved}
message Resource {
name: "cpus",
value: 2,
role: R,
reservation: STATIC
}
{code}
{code:title=3. dynamically reserved}
message Resource {
name: "cpus",
value: 2,
role: R,
reservation: DYNAMIC
}
{code}
Note that the following is invalid:
{code:title=invalid}
message Resource {
name: "cpus",
value: 2,
role: "*",
reservation: DYNAMIC
}
{code}
This is due to the fact that role="*" means *unreserved*.

> With the introduction of dynamic reservations, resources can be under one of
