Polybase：无法从 SQL Server 连接到 Azure Blob

Question

I am trying out the new Polybase-Feature in SQL-Server by connecting to a CSV . However I do not manage to connect to the Azure Blob Storage:

CREATE EXTERNAL DATA SOURCE AzureBlob WITH (
    TYPE = HADOOP,
    LOCATION = 'wasbs://myfolder@myblob.blob.core.windows.net',
    CREDENTIAL = mycredential
);
GO 

I always get an error saying:

Incorrect syntax near 'HADOOP'

My SQL Server runs on an Azure VM, however I am not sure which services are supposed to be running:

I also checked TCP/IP is enabled.

I also tried using SSDT and dsql-files as suggested in this post - but the error doesn't go away.

Answer 1

However I do not manage to connect to the Azure Blob Storage

Should it not be a Type=BLOB_STORAGE ?

CREATE EXTERNAL DATA SOURCE AzureBlob WITH (
    TYPE = BLOB_STORAGE,
    LOCATION = 'wasbs://myfolder@myblob.blob.core.windows.net',
    CREDENTIAL = mycredential
);

Update 2020-02-18:

I encounter the same famous message recently:

Incorrect syntax near 'HADOOP'

It can be fixed running:

exec sp_configure 'polybase enabled', 1;
GO
RECONFIGURE

Microsoft built a nice page: Configure PolyBase to access external data in Azure Blob Storage . However, they didn't include that important command.

I think it could also be a reason of the initial issue of 5th

Answer 2

While I accepted Alexander's answer, it turns out that the option BLOB_STORAGE doesn't allow to create external tables. The option HADOOP was the correct one for me. There were three steps I needed to do to make the HADOOP option work:

1. Re-install Java Runtime Environment
2. Repair the SQL Server Installation
3. Restart the Virtual Machine

Then the SQL -Statement from my question worked.
