Chun-Hung Hsiao created MESOS-9658:
--------------------------------------
Summary: Make command-line and/or environment variables be able to
unset a flag.
Key: MESOS-9658
URL: https://issues.apache.org/jira/browse/MESOS-9658
Project: Mesos
Issue Type: Improvement
Reporter: Chun-Hung Hsiao
Currently if a Mesos master/agent command-line flag is of type {{Option}}, the
only way to leave it as {{None}} is to unset the corresponding {{MESOS_}}
environment variable and don't specify the flag. Although this works, it would
be nice if the user could:
1. Override environment variable through command-line flags, e.g.
{{--feature_flag=none}}.
2. Override environment variable with another value, e.g.,
{{MESOS_FEATURE_FLAG=none}}. This is especially useful if users are managing
Mesos through systemd and specifying flags through environment files.
