-------------------------------
I tried a 0.98 shell against patched hbase2 and it fails the same way:
{code}
kalashnikov:hbase.git.clean stack$ ./bin/hbase shell

: 1 time, servers with issues: null location,
Here is some help for this command:
Put a cell 'value' at specified table/row/column and optionally
timestamp coordinates. To put a cell value into table 'ns1:t1' or 't1'
at row 'r1' under column 'c1' marked with the time 'ts1', do:
hbase> put 'ns1:t1', 'r1', 'c1', 'value'
hbase> put 't1', 'r1', 'c1', 'value'
hbase> put 't1', 'r1', 'c1', 'value', ts1
hbase> put 't1', 'r1', 'c1', 'value', {ATTRIBUTES=>{'mykey'=>'myvalue'}}
hbase> put 't1', 'r1', 'c1', 'value', ts1, {ATTRIBUTES=>{'mykey'=>'myvalue'}}
hbase> put 't1', 'r1', 'c1', 'value', ts1, {VISIBILITY=>'PRIVATE|SECRET'}
The same commands also can be run on a table reference. Suppose you had a
reference
t to table 't1', the corresponding command would be:
hbase> t.put 'r1', 'c1', 'value', ts1, {ATTRIBUTES=>{'mykey'=>'myvalue'}}
{code}
> Put back getClosestRowBefore and throw UnsupportedOperation instead... for
> asynchbase client

> 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.
