--------------------------------
Summary: Augment resource offers with Unavailability, given a
maintenance schedule
Key: MESOS-3038
URL: https://issues.apache.org/jira/browse/MESOS-3038
Project: Mesos
Issue Type: Task
Components: allocation, master
Reporter: Joseph Wu
Given a schedule, defined elsewhere, any resource offers to affected slaves
must include an Unavailability field.
The maintenance schedule for a single slave should be held in [persistent
storage|MESOS-2075] and locally by the master. i.e. In src/master/master.hpp:
{code}
struct Slave {
... // Existing fields.
// New field that the master/allocator can access
Maintenances pendingDowntime;
}
{code}
The new field should be populated via an API call (see [MESOS-2067]).
The Unavailability field can be added to Master::offer (src/master/master.cpp).
{code}
offer->mutable_unavailability()->MergeFrom(slave->pendingDowntime);
{code}
Possible test(s):
* PendingUnavailibilityTest
** Start master, slave.
** Check unavailability of offer == none.
** Set unavailability to the future.
** Check offer has unavailability.
