Phabricator updated HIVE-2958:
------------------------------
Attachment: HIVE-2958.D2871.1.patch
navis requested code review of "HIVE-2958 [jira] GROUP BY causing
ClassCastException [LazyDioInteger cannot be cast LazyInteger]".
Reviewers: JIRA
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:
