Bugs: MESOS-9523
https://issues.apache.org/jira/browse/MESOS-9523
Repository: mesos
Description
-------
This patch modifies the hierarchical allocator to take
framework-specified minimal allocatable resources into account.
While previously the allocator was inspecting the minimal allocatable
resources specified in its options, it now inspects a dynamically
calculated set of minimal allocatable resources. This set is populated
with any minimal allocatable resources specified in the allocator's
options and any framework's minimal allocatable resources. For a
resource to be allocatable it needs to contain any of these minimal
requirements.
If a framework does not specify minimal allocatable resource
requirements, its minimal requirements are set to the globally
configured option.
We also adjust the allocator to take a framework's minimal resource
requirements into account when checking whether a resource can be
allocated to a particular framework. The check is performed at the same
time we check whether a framework filtered a particular resource. This
avoids offering resources to frameworks which the framework would never
have considered allocatable itself (e.g., given the global option of the
allocator).
