Vitalii Diravka commented on DRILL-6145:
----------------------------------------
It is already supported in MapR Hive project:
[https://maprdocs.mapr.com/home/Hive/ConnectingToMapR-DB.html]
And supporting this can be added for Drill Project with using MapR profile, for
example.

> 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}
