Subject [jira] [Updated] (MESOS-2475) Add the Resource::ReservationInfo protobuf message
Date Mon, 23 Mar 2015 14:55:10 GMT

     [ https://issues.apache.org/jira/browse/MESOS-2475?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Park updated MESOS-2475:
--------------------------------
    Description: 
The {{Resource::ReservationInfo}} protobuf message encapsulates information needed to keep
track of reservations. It's named {{ReservationInfo}} rather than {{Reservation}} to keep
consistency with {{Resource::DiskInfo}}.

Here's essentially what it will look like in the end:

{code}
message ReservationInfo {
  // If this is set, it means that the resource is reserved for this particular
  // framework. Otherwise, the resource is reserved for the role.
  optional FrameworkID framework_id;

  // Indicates the principal of the operator or framework that created the
  // reservation. This is used to determine whether this resource can be 
  // unreserved by an operator or a framework by checking the
  // "unreserve" ACL.
  required string principal;

  // Anyone can set this ID at the time of reservation in order to keep track.
  optional string id;
}

// If this is set, this resource was dynamically reserved by an
// operator or a framework. Otherwise, this resource was
// statically configured by an operator via the --resources flag.
optional ReservationInfo reservation;
{code}

In v1, we'll only need to introduce {{framework_id}}. {{principal}} will be introduced along
with the "unreserved" ACLs and {{id}} may be introduced in the future.
