Ambari will take care of user and group creation once you start deploying the cluster

@Robin Dong The initial question was not clear. The main group is hadoop. You can setup permissions at directory and file level for users.

Check this https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/FileSystemShell.html

Look for chmod and chown commands
