> With HDFS-13017 and HDFS-13018 the cblock/jscsi server could be used in a
> kubernetes cluster as the backend for iscsi persistent volumes.
> Unfortunatelly we need to create all the required cblocks manually with 'hdfs
> cblok -c user volume...' for all the Persistent Volumes.
>
> But it could be handled with a simple optional component. An additional
> service could listen on the kubernetes event stream. In case of new
> PersistentVolumeClaim (where the storageClassName is cblock) the cblock
> server could create cblock in advance AND create the persistent volume could
> be created.
>
> The code is very simple, and this additional component could be optional in
> the cblock server.
