Assume that you install SQL Server 2017 on a computer that has Java SE RunTime Environment (JRE) version 9 installed. If you choose to install the PolyBase feature, the installer may not recognize JRE version 9 if you don't also have JRE version 7 or 8 installed. In this case, the installation of PolyBase may fail.


This fix is included in Cumulative Update 4 for SQL Server 2017.
