Major This is a far away task. Mainly because of Java 9 only available in 64-bit version. We can probably have installers with Java 8 32-bit and Java 9 64-bit, but that would be a nightmare to maintain, especially given nearly non existent maintainers/developers for Spark. We can still provide only Java 8 bundled installers until it is supported by Oracle and then think about switching to 9.
