Add multiple users in admin role without restarting

[mathes waran <ma...@gmail.com>]

Hi,
        I had set the property of  set.users.admin.role as

<property>
  <name>hive.users.in.admin.role</name>
  <value>user1,user2</value>
  <description>
    Comma separated list of users who are in admin role for bootstrapping.
    More users can be added in ADMIN role later.
  </description>
</property>

in hive-site.xml. If i want to add another users,stop the process and added
users to this property(admin role) for the purpose of* hive authorization*.Then
again i will started the process and working on it.But my point is *how to
add users to admin role without stopping and restarting the process.Is it
possible..?if i added any users name,i don't want to restart or stop
 the process,simultaneously i  want to execute it.*
