Phabricator updated HIVE-2828:
------------------------------

    Attachment: HIVE-2828.D1989.1.patch

navis requested code review of "HIVE-2828 [jira] make timestamp accessible in the hbase KeyValue".
Reviewers: JIRA

  DPAL-861 make timestamp accessible in the hbase KeyValue

  Originated from HIVE-2781 and not accepted, but I think this could be helpful to someone.

  By using special column notation ':timestamp' in HBASE_COLUMNS_MAPPING, user might access
timestamp value in hbase KeyValue.

  CREATE TABLE hbase_table (key int, value string, time timestamp)
    STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
    WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:string,:timestamp")

TEST PLAN
