I agree with Ryan, unless you can change the source version there's not that much point.
On the Hive front, as you can see from that ticket it's been open for 4(!) years and hasn't received much action recently. I think it's one of the reasons AWS EMR still defaults to Java 8. It would be really great if they could finally push that one over the finish line.
