I tried installing Raspbian Jessie, on the new Raspberry Pi 3 B+. The system did not boot, which I found was due to the old-code base. So, I am not sure if the Jessie option is a good one at this time.

Although, I was able to go through the steps with the Raspbian Stretch, with the Hadoop 2.6.5. I did not face issues I faced with Jessie.
