my Question is which Users are in the "public" group of Ranger? Is this group a wildcard only for all service users in the cluster (e.g. hive, spark ...) or is this group a wildcard for all users in the cluster, including the self made users?
In this documnetation i found the part:
What is the “public” group? Where did it come from?This is an internal group that serves as a wildcard for all system users.
For me it's not completly clear what "system" users in this context means.
By default all service users belong to public group. Service users are the users these services run as like hdfs, yarn, hive, hbase, ranger and so on.
Hope that helps answer your question.
