Sean Busbey commented on HBASE-15572:
-------------------------------------

The description is much better than previously. My request is for a description 
in the ref guide. That's the foundational layer for explaining to downstream 
folks how we expect them to use the features we create. There ought to be 
section already for hbase-spark, please add description / usage there.

> Adding optional timestamp semantics to HBase-Spark

> Right now the timestamp is always latest. With this patch, users can select 
> timestamps they want.
> In this patch, timestamp, minTimestamp and maxiTimestamp are added. Users can 
> select a timestamp, and can also select a time range with minimum timestamp 
> and maximum timestamp. A new test for selecting records with different 
> timestamps is added.
