Robert Stupp commented on CASSANDRA-8873:
-----------------------------------------
WDYT about the ability to override (nearly) every parameter in cassandra.yaml
using {{-Dcassandra.}} properties?
> Add PropertySeedProvider
> ------------------------
>
> Key: CASSANDRA-8873
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8873
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Albert P Tobey
> Priority: Minor
> Attachments: PropertySeedProvider.java
>
>
> 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"
