Dominic Hamon updated MESOS-1902: --------------------------------- Sprint: Twitter Q4 Sprint 1, Mesosphere Q4 Sprint 1 (was: Twitter Q4 Sprint 1) > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
