> During the downgrade process, run into the following error whilst it's
> restating Ranger Admin:
> {code}
> Traceback (most recent call last):
> File
> "/var/lib/ambari-agent/cache/common-services/RANGER/0.4.0/package/scripts/ranger_admin.py",

> raise Fail("Configuration parameter '" + self.name + "' was not found in
> configurations dictionary!")
> resource_management.core.exceptions.Fail: Configuration parameter
> 'kerberos-env' was not found in configurations dictionary!
> {code}
> The reason was that server did not have many configs selected, and did not
> send them to agent during downgrade. There are few issues here:
> - During upgrade from 2.4 to 2.5, finalize did not update current cluster
> version. As a result config helpers have gone mad
> - As a result of previous issue, some Configure tasks failed to execute
> - During downgrade from 2.6 , looks like cluster entity DB state was not
> consistent after config selection, so sometimes configs were not selected is
> some cases. I managed to reproduce that only once,
> it's a race condition that is very hard to catch/trace in debugger.
