Weiqing Yang updated HBASE-15572:
---------------------------------
    Description: 
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.

  was:
Right now the timestamp is always latest. With this patch, users can select timestamps they
want. 
In this patch, "TIMESTAMP ", "MIN_TIMESTAMP" and "MAX_TIMESTAMP" are added into HBaseSparkConf.
"TIMESTAMP" is the timestamp users select. For "MIN_TIMESTAMP" and "MAX_TIMESTAMP", users
can also select a time range with minimum timestamp and maximum timestamp. A new test for
selecting records with different timestamps is added.
