Can't start service cloudera-scm-server | Permission denied /etc/init.d/cloudera-scm-server

[#1]

I am unable to start service cloudera-scm-server owing to permission denied error. I am trying to set up Spark 2.0 in cloudera quickstart vm. After java 8 update , I am trying to start the server , but below error occurs. Any help will be

much appreciated.

[#2]

Please restart the service with root privileges e.g. 

# sudo service cloudera-scm-server restart

Note that force_start has a different purpose than helping over permissions issues.

sorry this did not work with restart, start, force_start anything. Same error I am getting.

Hi @Abhipreyo ,

Did you try with root user or sudo suggested by @gzigldrum? What is the CM version?

Thanks,

I tried with sudo.Nevertheless, issue is resolved now. 

After doing three four time reboot, it was solved.

But once I am trying to achieve my end goal which is to set up spark2 in cloudera. After every configuration I am trying to add service for Spark2. During First Run I am getting an error as givne below
