Hbase's timestamp attribute to be mapped for read or write, and then import data of timestamp to hbase's table from hive

      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)?

          What is the status of this ticket?
          Can someone tell me if this is going to be pushed? or any reason why its not pushed?

          This is a good feature and we have come to a couple of situations where this support is good to have.

          The current patch might not be applicable to the current version Hive 0.13, but I can work on it (in-fact I have a patch available with the current trunk but slightly different implementation).
