------------------------------

OK.  If you have a working copy, lets then merge what you have done here into hbase-1385.
 In hbase-1385, we'll do thinks like make versions configurable.  Thanks Jaehong Choi.

> I've seen a lot of changes in client APIs by HBASE-1304 patch.
> We can give a time range when we scan a table with assign TimeRange instance to Scan
class.
> I also see some code in org.apache.hadoop.hbase.mapreduce.TableInputForamtBase.java,
which uses a scan instance to get a Scanner instance.
> I think we can also give a time range to query when we do mapreduce on hbase. 
> I've already apply this one to my local copy for my purpose, which is about time series
analysis.
> Thanks.
