Welcome to my personal blog on digitalboys.

Time to upgrade from Cassandra 0.8.5 to 1.0.0
I have created a strategy where I split the cassandra data directories and the configuration directories apart. Diagrammatically: -
/opt/cassandra-dev/{
build/
cassandra-stress
cluster_config/{version}
apache-cassandra-{version}
etc..
Where cluster_config contains an environment variable initialiser; CASSANDRA_ENVIRONMENT.{sh,py} and the local cassandra rc scripts that map to the {version} of cassandra in question; e.g.
cluster_config/{version}/cassandra.in.sh (maps to CASSANDRA_ENVIRONMENT.sh)
Working fine 
Updates soon…
