Re: Users and Groups missing on the host

Are you installing as root?  I haven't had this specific problem, but you could just create the users and groups manually and re-run the inspector.  The problem I kept having was CM would not chown the directories correctly, and the HDFS service for example would fail to start because the DFS directory was owned by root instead of the hdfs user.
