Adam B commented on MESOS-1280:
-------------------------------
Replacing the command and URIs seems like part of an overall Update TaskInfo
epic, similar to Updating FrameworkInfo (MESOS-703) and Updating SlaveInfo
(MESOS-1739).
- Phase 1: updating the name, labels, and discoveryInfo.
- ReplaceTask phase, changing ExecutorInfo/CommandInfo/ContainerInfo.
- ResizeTask primitive, updating Resources.
- MigrateTask primitive: updating SlaveID.
- Other minor subtasks: Updating the HealthCheck, or task data.

> Key: MESOS-1280
> URL: https://issues.apache.org/jira/browse/MESOS-1280
> Project: Mesos
> Issue Type: Bug
> Components: c++ api, master, slave
> Reporter: Niklas Quarfot Nielsen
>
> Also along the lines of MESOS-938, replaceTask would one of a couple of
> primitives needed to support various task replacement and scaling scenarios.
> This replaceTask() version is significantly simpler than the first proposed
> one; it's only responsibility is to run a new task info on a running tasks
> resources.
> The running task will be killed as usual, but the newly freed resources will
> never be announced and the new task will run on them instead.
