-----------------------------
Assignee: Jie Yu
> Support persistent disk resource.
> ---------------------------------
>
> Key: MESOS-1902
> URL: https://issues.apache.org/jira/browse/MESOS-1902
> Project: Mesos
> Issue Type: Task
> Reporter: Jie Yu
> Assignee: Jie Yu
>
> Mesos needs to provide a way to allow tasks to write persistent data which
> won’t be garbage collected. For example, a task can write its persistent data
> to some predefined directory. When this task finishes, the framework can
> launch a new task which is able to access the persistent data written by the
> previous task which Mesos would have usually garbage-collected.
> One way to achieve that is to provide a new type of disk resources which are
> persistent. We call it persistent disk resource. When a framework launches a
> task using persistent disk resources, the data the task writes will be
> persisted. When the framework launches a new task using the same persistent
> disk resource (after the previous task finishes), the new task will be able
> to access the data written by the previous task.
> The persistent disk resource should be able to survive slave reboot or slave
> info/id change.
