Prior to SQL Server 2019 CTP 3.2, installing PolyBase required an installation of Oracle’s Java Runtime Environment 7 Update 51 or higher, either directly from Oracle or through OpenJDK.

Java is still required if you want to read from or write to Hadoop or Azure Blob Storage. Oracle’s flavor of Java is no longer required, however.
