   Hi All,

   I am facing errors running DSE 2.1 in analytic mode. It might be a configuration problem. Even i have seen similar sort of issues raised in forum previously http://www.datastax.com/support-forums/topic/cfs-is-not-accessable, still am unable to resolve the issue.

   Actually when i am using the command :
   dse hadoop fs -ls cfs://
   it is giving output as :
   /tmp
   /user
   Great. But next time when i am trying to execute :
   dse hadoop fs -ls cfs://user/
   it is not getting executed, rather showing timeout exception.

   Further using
   dse hadoop fs -copyFromLocal localpath/info.csv cfs://info.csv
   to copy file from local file system is getting executed successfully. But while trying to execute the following statement
   dse hadoop fs -cat cfs://info.csv
   its again throwing the same timeout exception

   Simply asking is it possible to store and retrieve files from cfs in DSE similar like HDFS.

   Your URIs are wrong.
   The correct URI syntax is:
   [cfs://[host][:port]]/[path]

   The cfs://user/ URI splits into the following components:

   scheme = cfs
   host = user
   path = /

   This is very likely not what you wanted and that's why it has connection problems.

   The following will work:

   dse hadoop fs -ls /user
   dse hadoop fs -ls cfs:///user
   dse hadoop fs -ls cfs://localhost/user

   dse hadoop fs -cat info.csv
   dse hadoop fs -cat cfs:///info.csv
   dse hadoop fs -cat cfs://localhost/info.csv
