> I have several large application/HBase clusters where an application node
> will occasionally need to talk to HBase from a different cluster. In order
> to help ensure some of my consistency guarantees I have a sentinel table that
> is updated atomically as users interact with the system. This works quite
> well for the "regular" hbase client but the REST client does not implement
> the checkAndPut and checkAndDelete operations. This exposes the application
> to some race conditions that have to be worked around. It would be ideal if
> the same checkAndPut/checkAndDelete operations could be supported by the REST
> client.
