          Description

          Hi,
          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 pablofdi@cosmos.lab.fi-ware.org

          1) I realize that there is no folder '/user/pablofdi' but '/home/pablofdi'.
          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/pablofdi/test

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

          Thanks!

            Hi,

            /home/<youruser> is created at Namenode OS, that's why you are seeing it if you perform a 'ls' command.

            /user/<youruser> is created at HDFS, an you can only list is by invoking 'hadoop fs -ls /user/<youruser>'

            Being said that, the Namenode of the FIWARE LAB instance recently entered in safe mode due to the disk is of the server is being consumed almost all. We are working on cleaning old files and unuseful stuff. Because the HDFS was in safe mode, the user creation was not completed at all. I've finished it manually, try it now, please.

            Regards,
            Francisco
