-----------------------------
Summary: Support persistent disk resource.
Key: MESOS-1902
URL: https://issues.apache.org/jira/browse/MESOS-1902
Project: Mesos
Issue Type: Task
Reporter: 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.
