Weiqing Yang commented on HBASE-15572:
--------------------------------------
(1) The name follows the convention of existing HBaseSparkConf. But you are
right, we may want to use hbase.spark instead of spark.hbase. I think it would
be better to solve it with a separate JIRA to change all these names in one
shot instead of introducing name inconsistency.
(2) Regarding the document JIRA, it does have some loose dependency, e.g., JSON
format, etc, DataFrame Rread/Writer, etc. Otherwise, it is hard to explain the
usage in a clear way. For [~zhanzhang] has already created jira HBASE-15473, I
think it is better to add more explanation on that jira.

> Right now the timestamp is always latest. With this patch, users can select
> timestamps they want.
> In this patch, 4 parameters, "timestamp", "minTimestamp", "maxiTimestamp" and
> "maxVersions" are added to HBaseSparkConf. Users can select a timestamp, they
> can also select a time range with minimum timestamp and maximum timestamp. A
> new test for selecting records with different timestamps is added.
