--------------------------------------
Summary: Introduce agent attributes that require frameworks to
"opt-in" for offers.
Key: MESOS-8785
URL: https://issues.apache.org/jira/browse/MESOS-8785
Project: Mesos
Issue Type: Epic
Components: agent, allocation, master, scheduler api
Reporter: Benjamin Mahler
In the past we have had cases of special agents (e.g. nodes with gpu, nodes
with non-default region) where we've added one off opt-in behavior for getting
offers from those nodes. This opt-in behavior for getting resources from these
agents has been based on framework capabilities (e.g. GPU_RESOURCES,
REGION_AWARE), however a generalized mechanism based on attributes would be
useful for future cases.
An "opt-in" agent attribute means that the framework has to opt-in its role(s)
to specific opt-in attributes in order to obtain resources from agents that
have the attribute.
For example, we have a cluster with 5 gpu nodes and want to ensure that these
are used for only gpu workloads. The operator would tag these machines with a
"gpu_workload" attribute and mark this attribute as opt-in. Now, only those
roles that frameworks opt-in to the "gpu_workload" attribute will receive
offers for these agents.
