Description

• Current column mapping dosn't support hbase's timestamp column to be mapped for read or write, and import data of timestamp to hbase's table from hive.

I find HIVE-1228 mentioned this issue,but not to address the :timestamp requirement at last. And https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration said that "there is currently no way to access the HBase timestamp attribute, and queries always access data with the latest timestamp."

Would allow timestamp to be map to hive(just like Get in hbase API) or "INSERT OVERWRITE TABLE hbase_table_1" with timestamp from hive(like Put in hbase API)?
