Benjamin Mahler created MESOS-7790:
--------------------------------------
Summary: Design hierarchical quota allocation.
Key: MESOS-7790
URL: https://issues.apache.org/jira/browse/MESOS-7790
Project: Mesos
Issue Type: Task
Components: allocation
Reporter: Benjamin Mahler
When quota is assigned in the role hierarchy (see MESOS-6375), it's possible
for there to be "undelegated" quota for a role. For example:
{noformat}
^
/ \
/ \
eng (90 cpus) sales (10 cpus)
^
/ \
/ \
ads (50 cpus) build (10 cpus)
{noformat}
Here, the "eng" role has 60 of its 90 cpus of quota delegated to its children,
and 30 cpus remain undelegated. We need to design how to allocate these 30 cpus
undelegated cpus. Are they allocated entirely to the "eng" role? Are they
allocated to the "eng" role tree? If so, how do we determine how much is
allocated to each role in the "eng" tree (i.e. "eng", "eng/ads", "eng/build").
