I got the idea for this from: http://wiki.apache.org/cassandra/StorageConfiguration
I put my keyspace setup on a webserver, and I pull it into the config like this: storage-conf.xml starts with: <!DOCTYPE storage [ <!-- include all these entities from external files--> <!ENTITY seeds SYSTEM "http://cassandraconfig /seeds.xml"> <!ENTITY autobootstrap SYSTEM "http://cassandraconfig /autobootstrap.xml"> <!ENTITY bumblekeyspace SYSTEM "http://cassandraconfig /bumblekeyspace.xml"> <!ENTITY listenaddress SYSTEM "listenaddress.xml"> <!ENTITY directories SYSTEM "directories.xml"> ]> Then further down: <Keyspaces> &bumblekeyspace; </Keyspaces> I didn't want to have to edit lots of files....
