<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.
