I have a problem on a CDH 5.8.0 parcels testsystem starting the Impala Catalog Server. 

The error message is the following: 

Can't open /var/run/cloudera-scm-agent/process/148-impala-CATALOGSERVER/supervisor.conf: Permission denied.

The permissions for this file are: 

-rw------- 1 root   root    2970 Jun 27 23:01 supervisor.conf

All other files and directories in the /var/run/cloudera-scm-agent/process/148-impala-CATLOGSERVER folder having owner impala and group  impala. 

When I change the permissions it will be overwritten on the next start. 

What is wrong here? 

And what needs to be changed. I recently installed a different service and changed the visudo file, but I have not changed the Impala configuration.

Thanks for the advice.
