Weiwei Yang commented on YARN-8811:
-----------------------------------
Hi [~eyang]
This scope limits us only to support storage volumes that compatible with CSI,
that means we can support NFS via a NFS CSI driver, something similar to [k8s
nfs-csi driver|https://github.com/kubernetes-csi/drivers/tree/master/pkg/nfs].
The source mount will be managed by YARN, more specifically its lifecycle is
managed by calling CSI driver's node stage/unstage/publish/unpublish APIs. This
means we are unable to support NFS gateway if already mounts HDFS to a local
filesystem, unless there is CSI driver for the gateway.
Thanks

> The Container Storage Interface (CSI) is a vendor neutral interface to bridge
> Container Orchestrators and Storage Providers. With the adoption of CSI in
> YARN, it will be easier to integrate 3rd party storage systems, and provide
> the ability to attach persistent volumes for stateful applications.
