Neil Conway updated MESOS-4421:
-------------------------------
Shepherd: Jie Yu
> Document that /reserve, /create-volumes endpoints can return misleading
> "success"
> ---------------------------------------------------------------------------------
>
> Key: MESOS-4421
> URL: https://issues.apache.org/jira/browse/MESOS-4421
> Project: Mesos
> Issue Type: Task
> Components: documentation, master
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: documentation, endpoint, mesosphere, persistent-volumes,
> reservations
>
> The docs for the {{/reserve}} endpoint say:
> {noformat}
> 200 OK: Success (the requested resources have been reserved).
> {noformat}
> This is not true: the master returns {{200}} when the request has been
> validated and a {{CheckpointResourcesMessage}} has been sent to the agent,
> but the master does not attempt to verify that the message has been received
> or that the agent successfully checkpointed. Same behavior applies to
> {{/unreserve}}, {{/create-volumes}}, and {{/destroy-volumes}}.
> We should _either_:
> 1. Accurately document what {{200}} return code means.
> 2. Change the implementation to wait for the agent's next checkpoint to
> succeed (and to include the effect of the operation) before returning success
> to the HTTP client.
