I'm in the process of rewriting our framework to take account of roles in mesos but am having trouble understanding the intended behaviour of roles.
If I have a slave started with --resources='cpus:4;cpus(role1):2' and a framework registered with a role of 'role1', the framework start receiving the role1 offer of 2 cpus as expected, but when I launch tasks for that offer using up all cpus, the framework starts receiving an offer of role '*' with 4 cpus while the 'role1' offers are busy / not available. Is this the intended behaviour? Is there any documentation on the behaviour of roles, weights, and how they are intended to be used/implemented? Radek
