[Fiware-lab-help] COSMOS public instance - ssh to Head node

Hi agin,

I have realize that COSMOS public instance creates new users according the
email at loging (name at server.com -> user:'name'). What happens if two
fi-lab users request COSMOS access?

Since I am able to ssh with a new user, now I can list the floders at
COSMOS, and I found that user 'pablo' exists since last year (2014-10-15) .
It seems to be a problem.

However, I can not find 'pablofdi' folder (my new user), and if I try to
make it:

[pablofdi at cosmosmaster-gi ~]$ hadoop fs -mkdir /user/pablofdi
mkdir: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot
create directory /user/pablofdi. Name node is in safe mode.

Thanks in advance.
