> CSI (Container Storage Interface) is a vendor neutral storage interface 
> specification for container orchestrators. CSI support is implemented in 
> YARN, Kubernetes and Mesos. Implementing a CSI server makes it easy to mount 
> disk volumes for containers.
> See https://github.com/container-storage-interface/spec for more details 
> about the spec.
> Until now we used https://github.com/CTrox/csi-s3 server to support CSI 
> specification. Using an ozone specific CSI server would have the following 
> advantages:
>  * We can provide additional functionalities (as we have access to the 
> internal Ozone API not just the very generic s3 api).
>  * Security setup can be synchronized.
>  * Increased stability
>  * Simplified deployment (only the minimal set of the components are required 
> to be installed)
> The CSI specification itself is very simple 
> (https://github.com/container-storage-interface/spec/blob/master/csi.proto) 
> at least the part which is required for Ozone.
> We can use various fuse s3 driver to mount the ozone buckets via s3.
