Klaus Ma commented on MESOS-3421:
---------------------------------
Correct my understanding on JIRA: it seems a requirement on {{Data Aware
Scheduling}} instead of Global Resources; Mesos need to 1.) prvoide a way for
user to publish data's location/info, 2.) provide a way for user to share
volume in slave hosts
So framework will implement {{Data Aware Scheduler}} based on #1; and when the
tasks are running in the slave host, they can share the volume by #2.
[~adam-mesos]/[~mcypark], any comments/suggestion?.

> 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.
