Expect result: run tensorflow jobs by normal user successfully
Root Cause: dockerPasswd.sh was exec by LSF Primary Admin, and will write files to CWD/OUTPUT_FILE_LOCATION. But LSF Primary Admin has no write permission if the workloads are ran by LSF Non-Primary Admin user.

Fix Solution: Provide write permission to OUTPUT_FILE_LOCATION.

Pls mail me or append your concern here if any issues, Thanks.
