[~weiqing] Can you please add a description in the
./src/main/asciidoc/_chapters/spark.adoc as requested.
[~busbey] There is a document JIRA opened for the new Dataframe user interface
and features. The PR is not sent yet, because currently there is still a number
of place needed to be changed in the DataFrame support for HBase. Once it is
done, a more complete doc will be sent for the community review. To make the
work more trackable, I create a link for this jira to
https://issues.apache.org/jira/browse/HBASE-14789.

> 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.
