(1) I will submit v9 which renames ’timestamp’ to be
“spark.hbase.query.timestamp”, as well as the other three parameters in
SparkHBaseConf.
{quote}
Is there a reason this can't be "hbase.spark.query.timestamp" ?
{quote}
Yes, you are right. A code example will make it clear, so I will add more
detailed description in HBASE-15473: Documentation for the usage of hbase
dataframe user api (JSON, Avro, etc).
{quote}
I would like documentation complete as a part of adding this feature rather
than as a follow on. Is there some reason we can't document this addition
unless we also document the use of JSON, Avro, etc?

> 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.
