在 SQL Server 2019 中安装 PolyBase 时出错

Question

I'm trying to install Polybase in SQL Server 2019, but I keep getting following error:

Error installing SQL PolyBase
User, group, or role 'NT Authority\\NETWORK SERVICE' already exists in the current database. Changed database context to 'DWDiagnostics'.
Error code: 0x84BB0001

I'm doing everything just like in documentation ( https://docs.microsoft.com/en-us/sql/relational-databases/polybase/polybase-installation?view=sql-server-ver15 ). What should I do to fix this issue?

您不能使用任何系统帐户进行​​安装，您需要域帐户或具有管理员角色的新用户。
