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.

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:
<property>
<name>dfs.cluster.administrators</name>
<value></value>
<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.
