[jira] [Commented] (CASSANDRA-5067) Allow basic yaml properties to be specified via JVM parameters

["Ahmed Bashir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13531542#comment-13531542 ] 

Ahmed Bashir commented on CASSANDRA-5067:
-----------------------------------------

listen_address and rpc_address can be auto-resolved to 'hostname', but that would not work if there were multiple instances of Cassandra running on a physical host.

> 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.
