title: include file ,exclude file - permission clarification hadoop
body: <p>I am new to hadoop . 
  using Hadoop 2.3.0-cdh5.0.0 </p>
  
  <p>In the process of  adding and decommission of datanode in multi node cluster .
  Read about the steps in the book. 
  I really got stuck in the middle as to what permission(user:group) should be set for include and exclude file which should reside on the local system of the namenode running .
  Also it will be much helpful if anyone can give me a example as to how include and exclude file will look. 
  I assume we just need to add the Network address of the datanode cluster in each of the file.
  Correct me if I am wrong.</p>
  
  <p>Thanks</p>
