Btw @dbeech is this 'temporary' workaround still needed in the playbook (maybe for older CDH 5.x versions ?).
During my initial tests with CDH 6.2, I had this part ignored, and the deployment worked (at least upto the CM install + configuration)

No, I don't think this is required any more. The bug listed is 3 years old and wasn't even commonly encountered -- I think the original root cause was that selinux was enabled and this messed up the user creation through CM.

OK, then I propose to get that whole logic out in a future PR
( but keep my addition in for now, assuming you are OK with the rest)
