Subject Dynamic Resource Roles
Date Wed, 10 Sep 2014 14:49:10 GMT
Hey everyone,

Just a quick question. Has the ever been any discussion around dynamic

What I mean by this – currently if I want to guarantee 1 core and 10 GB of
ram to a specific type of framework (or "role") I need to do this at a
slave level. This means if I only want to guarantee a small number of
resources, I could do this on one slave. If that slave dies, that resource
is no longer available.

It would be interesting to see the master (DRF scheduler) capable of
reserving a minimum about of resource for offering only to frameworks of a
certain role, such that I can guarantee R amount of resources on N slaves
across the cluster as a whole.
