Andrew Purtell updated HBASE-14122:
-----------------------------------
Attachment: HBASE-14122.patch
Patch implements the proposal. Adds a new shell command too. Since the answer
to the question "what security features are supported?" varies depending on the
set of installed coprocessors we return a set of capabilities contributed by
base HBase and any installed coprocessors.
Except: The proposed throw of UnsupportedOperationException. Instead it's an
IOException. This is because what is unwrapped from the server is not an UOE
and it would take matching over the message string to distinguish a UOE. (That
is what the shell does to respond with a nice message.) Could do it in the API
too but that would be brittle.

> Add a client API for determining if the server side supports cell level
> security.
> Ask the master, assuming as we do in many other instances that the master and
> regionservers all have a consistent view of site configuration.
> Return {{true}} if all features required for cell level security are present,
> {{false}} otherwise, or throw {{UnsupportedOperationException}} if the master
> does not have support for the RPC call.
