if you manually modify the supervisor.conf permission:

chmod +020 supervisor.conf

restart Load Balancer, in the CM interface will generate a new directory / opt/cm-5.14.1/run/cloudera-scm-agent/process/114-hue-HUE_LOAD_BALANCER/. Prompt the same error.

Mar.01,2021

reason: httpd,mod_ssl service is not pre-installed in the server environment

solution:

yum-y install httpd

yum-y install mod_ssl


look at the error, I think the mod_ssl is not installed
