BenŠ There is a similar issue with distributing keytab files when enabling Kerberos. To do this, we needed to write custom Java code in Ambari to execute server-side actions that generated the data and setup tasks to distribute some of it (namely keytab files) to the relevant hosts. Unfortunately this was not built generically so there is no good place for you to hook into - new classes must be created. Maybe we can come up with a way to do this more generically and push task implementation into Python scripts to that live in the stack definitions.
Other than that, I don¹t really have an good ideas to help your scenario.
