> First, I put a cell using put interface, but I don't specify timestamp. Then I delete
the the same row, specify a timestamp of 1L. Unfortunately, the former cell is 
> deleted. We should know this cell can not be deleted in this case. (Using original Client
API)
> Code like this;
> public static void main(String[] args) throws Exception {
>         Cluster cluster = new Cluster();
>         cluster.add("10.28.171.38", 8080);
>         Client client = new Client(cluster);
>         RemoteHTable table = new RemoteHTable(client, "demotime");
>                 
>         Put put = new Put(Bytes.toBytes("row21"));
>         put.add("info".getBytes(), "name".getBytes(), "huanggang".getBytes());
>         table.put(put);
>         
>         Delete delete = new Delete(Bytes.toBytes("row21"));
>         delete.setTimestamp(1L);
>         table.delete(delete);
>     }
