Configure SQL PolyBase to access external data in MongoDB - problem

Question

Im trying to connect SQL server using Polybase with MongoDB but Im failing to create the external data source for that. Please help ...

Im using the following code:

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'mypassword';  

CREATE DATABASE SCOPED CREDENTIAL MongoDbUser
WITH IDENTITY = 'myusername', Secret = 'thepassword';


CREATE EXTERNAL DATA SOURCE external_DS_MongoDB
WITH (
TYPE = HADOOP,
LOCATION = 'mongodb://localhost:27017', 
CREDENTIAL = MongoDbUser
);

Im expecting the create the datasource with name "external_DS_MongoDB" but Im facing the following error in SQL:

Msg 105007, Level 16, State 1, Line 26 Scheme of the input URI is not supported. Please revise the following scheme and try again: 'mongodb'

Can anybody advice me ?

Thanks.

TYPE is not needed when creating a MongoDB data source:

CREATE EXTERNAL DATA SOURCE external_DS_MongoDB
WITH 
(
LOCATION = 'mongodb://localhost:27017', 
CREDENTIAL = MongoDbUser
);
