I like to change file permissions for security hardening These files have 'w' bit in others, is it possible to change to 220 manually? --w--w--w- 1 root root 0 Oct 29 18:41 /var/run/cloudera-scm-agent/cgroups/memory/<service_name>/cgroup.event_control --w--w--w- 1 root root 0 Oct 29 18:43 /var/run/cloudera-scm-agent/cgroups/memory/<service_name>/cgroup.event_control   These files are newly created every time that the service is started, can permissions be set to 220 permanently instead of manually? This change may cause problems with the service?   Thanks ... View more
