          Question:
          SafeModeException at cosmos.lab.fi-ware.org

          Description:
          According to the wiki

          http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/BigData_Analysis_-_Quick_Start_for_Programmers#Step_1._Create_a_Cosmos_account

          and via

          ssh my_user@cosmos.lab.fi-ware.org

          1) I realize that there is no folder '/user/my_user' but '/home/my_user'. Why? May I suposse that my user is not propertly created?

          2) I am trying to create a folder, but I get the SafeModeException:

          hadoop fs -mkdir /home/my_user/test

          mkdir: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory /home/my_user/test. Name node is in safe mode.

          I have tried:

          hadoop dfsadmin -safemode leave

          with this result:

          safemode: org.apache.hadoop.security.AccessControlException: Access denied for user my_user. Superuser privilege is required

          Thanks!
