Review request for mesos, Alexander Rukletsov, Benjamin Hindman, Ben Mahler,
and Jie Yu.
Changes
-------
Updated **Description** to reflect the change of pattern from
`sum(resources.values())` to `sum(resources)`.
Bugs: MESOS-2373
https://issues.apache.org/jira/browse/MESOS-2373
Repository: mesos
Description (updated)
-------
This is the start of a patch chain for converting `Resources` to
`hashmap<SlaveID, Resources>` in places where we have an aggregate of resources
across multiple slaves. In short, scalar resources aggregate correctly across
multiple slaves, but non-scalar resources (e.g. ports) do not aggregate
correctly. Please refer to the JIRA ticket for further details.
The function `sum` is factored out to facilitate small patches. The following
is the strategy and why this function will be useful:
(1) Update a variable `resources` in a component (e.g. master) from `Resources`
to `hashmap<SlaveID, Resources>`.
(2) For callsites where we pass `resources` to another component (e.g.
allocator), we'll pass `sum(resources)` instead to preserve the existing
behavior in the other component.
