One other thing, that seems to catch me every time I upgrade an old instance: you will need to go in and allow users to read provenance data again. Somewhere along the way (1.6?) provenance reading moved into a separate policy, and it does not get assigned to anyone after upgrade.

Hi, I have just one data point on the version but I would suggest moving to 1.9 if you're just starting out and if you're using the Record based processors with potentially dynamic/changing schemas. The automatic schema inference described in this blog post[1] makes things much easier (or possible). I see no reason to start with 1.8 today if you have the option of upgrading. Java: Java 8, while outdated, is still pretty much standard almost everywhere I look.
