The tasks here are not required if "11.1.3 Configure SSH Authentication Keys to be Used by the Cache Local Feature" was implemented.
As authentication key checking is performed during the MapReduce job user authentication of the DFS, an authentication key file must be created in advance. Use the pdfs.security.authorization property in pdfs-site.xml to set whether or not job user authentication is used. The default is "false" (disabled).
Note that the tasks below are not required if "false" (disabled) is set for pdfs.security.authorization.
Refer to "C.4 pdfs-site.xml" for information on the pdfs.security.authorization property.
Example
If the user is bdppuser1 and the DFS mount directory is /mnt/pdfs:
As the settings are shared at all nodes, bdppuser1 executes as shown below at any of the nodes where the DFS is mounted.
$ cd ~ <Enter> $ cat > id_hadoop <Enter> anyKeywordString ctrl-d $ hadoop fs -mkdir .pdfs <Enter> $ hadoop fs -chmod 700 .pdfs <Enter> $ hadoop fs -moveFromLocal id_hadoop .pdfs/ <Enter> $ hadoop fs -chmod 600 .pdfs/id_hadoop <Enter>
