> Project: Hive
> Issue Type: New Feature
> Components: HBase Handler
> Affects Versions: 0.14.0
> Reporter: Muhammad Ehsan ul Haque
> Priority: Minor
> Fix For: 0.14.0

> Previous attempts HIVE-2781 (not accepted), HIVE-2828 (broken and proposed with restricted feature).
> The feature is to have hbase cell latest timestamp accessible in hive query, by mapping the cell timestamp with a hive column, using mapping format like
> {code}:timestamp:cf:[optional qualifier or qualifier prefix]{code}
> The hive create table statement would be like
> h4. For mapping a cell latest timestamp.
> {code}
> CREATE TABLE hive_hbase_table (key STRING, col1 STRING, col1_ts BIGINT)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:qualifier, :timestamp:cf:qualifier")
> TBLPROPERTIES ("hbase.table.name" = "hbase_table");
> {code}
> h4. For mapping a column family latest timestamp.
> {code}
> CREATE TABLE hive_hbase_table (key STRING, valuemap MAP<STRING, STRING>, timestampmap MAP<STRING, BIGINT>)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:,:timestamp:cf:")
> TBLPROPERTIES ("hbase.table.name" = "hbase_table");
> {code}
> h4. Providing default cell value
> {code}
> CREATE TABLE hive_hbase_table(key int, value string, value_timestamp bigint)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = "cf:qualifier, :timestamp:cf:qualifier",
> "hbase.put.default.cell.value" = "default value")
> TBLPROPERTIES ("hbase.table.name" = "hbase_table");
> {code}
