> dfs.cluster.administrators handles values of the following format:
>     
>     
>     CL for the admins, this configuration is used to control who can access the default
servlets in the namenode, etc. The value should be a comma separated list of users and groups.
The user list comes first and is separated by a space followed by the group list, e.g. "user1,user2
group1,group2". Both users and groups are optional, so "user1", " group1", "", "user1 group1",
"user1,user2 group1,group2" are all valid (note the leading space in " group1"). '*' grants
access to all users and groups, e.g. '*', '* ' and ' *' are all valid. 
>     
> Ambari cannot handle * value correctly it will try to create a group or user
> named '*'.  
> Also Ambari cannot correctly create groups if there are multiple spaces
> instead of one.
