Vitalii Diravka updated DRILL-6145:
-----------------------------------
    Description: 
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}
hive> 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 via Drill:
{code}
0: jdbc:drill:> select * from hive.mapr_db_json_hive_tbl;
{code}
