HIVE-2958 [jira] GROUP BY causing ClassCastException [LazyDioInteger cannot
be
cast LazyInteger]
(Navis Ryu via Ashutosh Chauhan)
Summary:
DPAL-1111 GROUP BY causing ClassCastException [LazyDioInteger cannot be cast
LazyInteger]
This relates to https://issues.apache.org/jira/browse/HIVE-1634.
The following work fine:
CREATE EXTERNAL TABLE tim_hbase_occurrence (
id int,
scientific_name string,
data_resource_id int
) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH
SERDEPROPERTIES (
"hbase.columns.mapping" = ":key#b,v:scientific_name#s,v:data_resource_id#b"
) TBLPROPERTIES(
"hbase.table.name" = "mini_occurrences",
"hbase.table.default.storage.type" = "binary"
);
SELECT * FROM tim_hbase_occurrence LIMIT 3;
SELECT * FROM tim_hbase_occurrence WHERE data_resource_id=1081 LIMIT 3;
However, the following fails:
SELECT data_resource_id, count(*) FROM tim_hbase_occurrence GROUP BY
data_resource_id;
The error given:

> 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.
