--------------------------------------
Summary: Implement Hive MapR-DB JSON handler.
Key: DRILL-6145
URL: https://issues.apache.org/jira/browse/DRILL-6145
Project: Apache Drill
Issue Type: Bug
Components: Storage - Hive, Storage - MapRDB
Affects Versions: 1.12.0
Reporter: Vitalii Diravka
Assignee: Vitalii Diravka
Fix For: 1.13.0
Similar to "hive-hbase-storage-handler" to support querying MapR-DB Hive's
external tables it is necessary to add "hive-maprdb-json-handler".
Use case:
# Create a table MapR-DB JSON table:
{code}
_> mapr dbshell_
_maprdb root:> create /tmp/table/json_ (make sure /tmp/table exists)
{code}
-- insert data
{code}
insert /tmp/table/json --value '\{"_id":"movie0000002" , "title":"Developers on
the Edge", "studio":"Command Line Studios"}'
insert /tmp/table/json --id movie0000003 --value '\{"title":"The Golden
Master", "studio":"All-Nighter"}'
{code}
# Create a Hive external table:
{code}
CREATE EXTERNAL TABLE mapr_db_json_hive_tbl (
movie_id string, title string, studio string)
STORED BY 'org.apache.hadoop.hive.maprdb.json.MapRDBJsonStorageHandler'
TBLPROPERTIES("maprdb.table.name" = "/tmp/table/json","maprdb.column.id" =
"movie_id");
{code}
# Use hive schema to query this table:
{code}
select * from hive.mapr_db_json_hive_tbl;
{code}
