> Mesos should support adding volumes to launched taskManagers
> ------------------------------------------------------------
>
> Key: FLINK-5975
> URL: https://issues.apache.org/jira/browse/FLINK-5975
> Project: Flink
> Issue Type: Improvement
> Components: Mesos
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Addison Higham
> Priority: Minor
>
> Flink needs access to shared storage.
> In many cases, this is HDFS, but it would be nice to also support file URIs
> on an mounted NFS for example.
> Mesos exposes APIs for adding volumes, so it should be relatively simply to
> add this.
> As an example, here is the spark code for supporting volumes:
> https://github.com/apache/spark/blob/master/resource-managers/mesos/src/main/scala/org/apache/spark/scheduler/cluster/mesos/MesosSchedulerBackendUtil.scala#L35
