Phabricator updated HIVE-1634:
------------------------------
Attachment: HIVE-1634.D1581.2.patch
ashutoshc updated the revision "HIVE-1634 [jira] Allow access to Primitive
types stored in binary format in HBase".
Reviewers: JIRA, jsichi
Fixed couple of bugs in testcases. Now all the tests pass.
Refactored to move new introduced classes in their own package
serde2.lazydio. Also named classes as LazyDioInteger and so on.

> Key: HIVE-1634

> Project: Hive
> Issue Type: Improvement
> Components: HBase Handler
> Affects Versions: 0.7.0, 0.8.0, 0.9.0
> Reporter: Basab Maulik
> Assignee: Ashutosh Chauhan
> Attachments: HIVE-1634.0.patch, HIVE-1634.1.patch,

> This addresses HIVE-1245 in part, for atomic or primitive types.
> The serde property "hbase.columns.storage.types" = "-,b,b,b,b,b,b,b,b" is a
> specification of the storage option for the corresponding column in the serde
> property "hbase.columns.mapping". Allowed values are '-' for table default,
> 's' for standard string storage, and 'b' for binary storage as would be
> obtained from o.a.h.hbase.utils.Bytes. Map types for HBase column families
> use a colon separated pair such as 's:b' for the key and value part
> specifiers respectively. See the test cases and queries for HBase handler for
> additional examples.
> There is also a table property "hbase.table.default.storage.type" = "string"
> to specify a table level default storage type. The other valid specification
> is "binary". The table level default is overridden by a column level
> specification.
> This control is available for the boolean, tinyint, smallint, int, bigint,
> float, and double primitive types. The attached patch also relaxes the
> mapping of map types to HBase column families to allow any primitive type to
> be the map key.
> Attached is a program for creating a table and populating it in HBase. The
> external table in Hive can access the data as shown in the example below.
