Configuring a Cassandra cluster
Now that you have a single node setup, you may start Cassandra by executing <cassandra_installation>/bin/cassandra for a tarball install or by running sudo service cassandra start for a repository install. (We'll see later in this chapter how to write a .init script for Cassandra and set it up to start on boot.) However, in order to get a Cassandra cluster working, a couple of configuration tweaks are required.
If you look at cassandra.yaml, you will find that it has the following six sections:
Cluster setup properties: These are basically startup properties, file location, ports, replica placement strategies, and internode communication settings.
Performance tuning properties: These help in setting up appropriate values for system and/or network resources on the basis of your setup.
Client connection properties: These help in setting up the behavior of client-to-node connectivity, namely the number of requests per client or maximum number of threads...
