Looking to start using SQL Server 2019 and have some questions...
1. Would MS support be able to assist with Hadoop issues? What support is available for MSSQL Server 2019 enterprise customers?
2. Does MSSQL Server need to be installed on any particular kind of OS to use polybase (eg. Linux vs Windows installation matter for accessing a local Linux Hadoop cluster)?
3. What kind of files / data can be accessed from polybase?
Thank you.
