RM through command line

studhadoop

hai ,

I am running rapidminer in my root (mac)
i am able to run my process through commandline from root.

_{Stud-2:rapidminer root# ./scripts/rapidminer //GraphRepo/Processes/clsperf}

my process is within root (where rapidminer is installed)
Now i need to execute this process from _{Stud-2:~ stud$} by giving root permission

so far what i did is
1.able to execute a process as command line from root
2.so i wrote a shell script runasroot.sh  
   _{vi runasroot.sh
           sudo -s './runrapid.sh'}
3 and in runrapid.sh
  vi runrapid.sh
            _{cd var/root/rapidminer
            ./scripts/rapidminer //GraphRepo/Processes/clsperf}
4.then i did ./runasroot.sh
           showing
                     _{WARNING: Unable to create user home rapidminer directory /Users/stud/.RapidMiner5
                     java.io.FileNotFoundException: /Users/amrita/.RapidMiner5/cipher.key (No such file or directory)
                    com.rapidminer.tools.cipher.KeyGenerationException: Cannot store key: /Users/amrita/.RapidMiner5/cipher.key (No such file or directory)
                   java.io.IOException: Cannot locate entry '//GraphRepo/Processes/clsperf': com.rapidminer.repository.RepositoryException: Requested repository GraphRepo does not exist.
                   Caused by: com.rapidminer.repository.RepositoryException: Requested repository GraphRepo does not exist}

why is it so .
actually when i am doing sudo -s command ,it is running as root ,right?. so it is already creating /var/root/.RapidMiner5
i also given stud the privilege to access root without password

i ran runrapid.sh in root successfully
what is the problem
