>> I think this a JIRA that we should file against KSM.
I will create a JIRA to track the same
HDFS-12144 is for tracking the issue

> {{OzoneClient}} interface defines all the client operations supported by Ozone. 
> {{OzoneClientImpl}} will have the default implementation, it should connects to KSM,
SCM and DataNode through RPC protocol to execute client calls.
> Similarly we should have a client implementation which implements {{OzoneClient}} and
uses REST protocol to execute client calls.
> This will provide lots of flexibility to Ozone applications, when applications are running
inside the cluster, they can use RPC protocol, but when running from outside the cluster,
the same applications can speak REST protocol to communicate with Ozone.
