      Description

      We are having troubles with COSMOS. We have no permissions to do
      actions through SSH in our directory. For example:

      hadoop fs -cat /user/antonio.gonzalez/

      Thanks in advance

          Hi,

          We agree with Miguel from Talkykar. We have trying to perform some basic
          operations with COSMOS following the tutorials but it does not work.

          Regards
          Ignacio

          Hi,

          your HDFS userspace has the right permissions:

          1. hadoop fs -ls /user | grep antonio.gonzalez
            drwxr----- - antonio.gonzalez antonio.gonzalez 0 2015-07-03 10:43 /user/antonio.gonzalez

          I guess you have ssh'ed into the Namenode (cosmos.lab.fiware.org) as antonio.gonzalez and have tried to perform some hadoop fs command; can you confirm that? If you logged as any other user, you wont be able to see the contents of any other user.

          By the way, hadoop fs -cat lists the content of a file, and /user/antonio.gonzalez is a directory. Try doing:

          $ hadoop fs -ls /user/antonio.gonzalez

          Regards,
          Francisco
