Sql Server 2019 Polybase 功能问题

Question

I'm trying to configure PolyBase on SQL Server 2019 to test some new features.

I already installed this feature and performed all steps from below instruction:
Install PolyBase on Windows

I get an error notification when trying to configure connection to external table in Azure Data Studio:

I cannot start the SQL Server PolyBase Engine service, maybe it has something to do in this case:

Any ideas how to configure it properly to use PolyBase?

Answer 1

在启动服务之前，您需要为此 SQL Server 启用 TCP/IP

Answer 2

You need to:

• enable TCP/IP as network protocol for your SQL Server instance.
• Restart the SQL Instance Restart the Polybase services.
• Enable PolyBase on the instance: exec sp_configure @configname = 'polybase enabled', @configvalue = 1; RECONFIGURE; exec sp_configure @configname = 'polybase enabled', @configvalue = 1; RECONFIGURE; .
