---------------------------------
Summary: Improve the allocator so that it does not send cpu only
or mem only resources in certain cases
Key: MESOS-8938
URL: https://issues.apache.org/jira/browse/MESOS-8938
Project: Mesos
Issue Type: Improvement
Components: allocation
Reporter: Vinod Kone
MESOS-1688 changed the allocator behavior so that it can offer cpu only or
memory only resources to frameworks, but this is not always useful. For
example, if a framework has never launched an executor/container on an agent,
it doesn't make sense to send it a cpu only or memory only offer. Once a
framework launches an executor, it could use cpu only or memory only offers to
grow the size of the executor.
This ticket tracks an improvement to the "isAllocatable()" function to make it
more smart as discussed above. This is important to improve pathological
situations like MESOS-8937.
