Hello Tallenl,

This property supports multiple users and groups.  The documentation for this property describes
the syntax, but that documentation is not yet live on hadoop.apache.org.  Here is a copy of
that documentation content from trunk:

   <description>ACL 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.

Subject: Multiples dfs.cluster.administrators

Hello !

I send you this mail because I need to set multiple users with the same powers than hdfs in
my hadoop cluster.

Do you know if it is possible with the property dfs.cluster.administrators ?
Do we put user or group in this property ?
If I can put multiple items in this property, do you know what is the delimiter ?

Best regards.
