Klaus Ma commented on MESOS-3421:
---------------------------------
[~anindya.sinha], here's my understanding about your requirements; if wrong,
please correct me:
1. The resources are shared: if one task use it, the number will NOT
decrease; the resources are destroy explicitly (e.g. DELETE)
2. In slave hosts, executor need the permission/info to access it
3. The shared resources are not hard requirements of the task: if there's
no volume in the slave, the tasks are also finished successfully
[~adam-mesos], I think this is a new requirement against Global Resources:
different with License, Network, the resources are re-usable in this
requirement. I'll add it as a new requirement into Global Resources.
If any comments, please let me know.
> Support sharing persistent volumes across task instances

> Key: MESOS-3421
> URL: https://issues.apache.org/jira/browse/MESOS-3421
> Project: Mesos
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.23.0
> Reporter: Anindya Sinha
> Assignee: Anindya Sinha
>
> A service that needs persistent volume needs to have access to the same
> persistent volume (RW) from multiple task(s) instances on the same agent
> node. Currently, a persistent volume once offered to the framework(s) can be
> scheduled to a task and until that tasks terminates, that persistent volume
> cannot be used by another task.
> Explore providing the capability of sharing persistent volumes across task
> instances scheduled on a single agent node.
