Subject [jira] [Commented] (CASSANDRA-5067) Allow basic yaml properties to be specified via JVM parameters
Date Mon, 11 Feb 2013 17:43:13 GMT


Brandon Williams commented on CASSANDRA-5067:

bq. specified on the command line in some canonical form (numbers, strings, lists, etc)

Perhaps we could use a serialization format, like yaml?  All kidding aside, it's as valid
a choice as any, and illustrates how we're relocating, rather than solving a problem by doing

> 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.
