> asychbase can work against all hbase versions. This fact has saved us a few
> times; e.g. LINE were able to migrate from 0.94 to 1.2 going in part via
> asynchbase and its ability to work against all servers.
> hbase2 breaks this ability of asynchbase. There is nothing for asynchbase to
> figure definitively that it is talking to an hbase2 server (See HBASE-20225).
> Lets add back something it can leverage. HBASE-13954 did a nice job purging
> getClosestRowBefore. Lets put back an RPC stuff that throws an exception if
> it gets called. Thats enough for asynchbase.
