Create user accounts in advance at all nodes comprising the DFS. At that time, ensure the correspondence between user names and user IDs is the same at all nodes. This is to achieve consistency at all nodes because DFS uses the user IDs for control and Hadoop operates on the basis of user names.
Create a user home directory (${pdfs.fs.local.homedir}/<user name>) under the DFS FileSystem class.
Example
If the user is called bdppuser1:
Since the settings are shared at all nodes, execute as shown below at any of the nodes where DFS is mounted.
Execute using root permission.
$ su # hadoop fs -mkdir /user/bdppuser1 # hadoop fs -chown bdppuser1:bdppgroup /user/bdppuser1 # hadoop fs -chmod 0700 /user/bdppuser1 # exit
Set Group and Permission to suit the environment being used.
