There are currently two places in puppet that have a lot of unnecessary configs (that could be replaced with sane defaults):
- common.yaml - we should review common configs for the Hadoop clusters, adding good defaults to profile::hadoop::common etc..
- The use_kerberos settings are redundant now, all clusters that we run have and will have kerberos enabled. We should remove what it is not needed and think about a solution for labs/cloud (like adding a conditional to kerberos::systemd_timer and exec for example).
