Hello, I do know scenarios which involve sticking with Java 6. Mostly related to supporting Applications Servers of (Big) 3 Letter companies (both).
I dont see that in an Hadoop cluster. Especially given that expressiveness of Java 8 and also Performance of Java 7 are both important in Big Data analytics an das hoc Job platforms. So I would really be Suprised if any user Organisation would wand a major Hadoop upgrade but sticking with an unsupported / outdated JVM. Greetings Bernd (Who still ships 1.4 products)
