Robert Stupp commented on CASSANDRA-8873:
-----------------------------------------

WDYT about the ability to override (nearly) every parameter in cassandra.yaml using {{-Dcassandra.}} properties?

> Add a PropertySeedProvider that allows administrators to set a seed on the command line with -Dcassandra.seeds=127.0.0.1,127.0.0.2 instead of rewriting cassandra.yaml.
> It looks like the yaml parser expects there to always be a parameters: option on seeds, so unless we change it to be optional, there needs to be a dummy map or the yaml will not parse, e.g.
> seed_provider:
>     - class_name: org.apache.cassandra.locator.PropertySeedProvider
>       parameters:
>           - stub: "this is required for the yaml parser and is ignored"
