> # services with no configurations input (config-type key not provided)
> The second case happens when I am editing only YARN service configs, and I do
> not have configs for all the other services. In such a case, the
> configs-validation call is made with only YARN config-types (yarn-env,
> yarn-site, etc.). All other config-types are not provided. So for such a
> call, validation for other services (Oozie, HDFS, etc. should not be
> performed). So, basically we validate a service configs, only if its
> config-types are present.
