Description

In the case of large clusters, each node operates with a cassandra.yaml that is nearly identical to every other node with the exception of some basic properties:

listen_address
rpc_address
initial_token
data_file_directories
etc

If it was possible to specific these as JVM parameters, we wouldn't have to prepare a customized cassandra.yaml for each node but rather share a single cassandra.yaml file. This is increasingly important when the number of nodes being managed gets very large.
