Jerry He commented on HBASE-15572:
----------------------------------
bq> Does this only let folks choose timestamp ranges in SparkSQL? Or does it
also work for the other HBase query mechanisms, like the hBaseRDD described in
the Basic Spark section of the ref guide?
I think they are only used for SparkSQL, to pass property option to SparkSQL
and to data source class. hbaseRDD takes SCAN object, which would contains
everything.

> 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.
