Last we had to remove all the files in /var/lib/cassandra/ simply because somewhere it break when we upgraded from cassandra 2.0.0 to 2.0.2 and everybody in the teams just do not have the time to goes into details. So since this is just4fun cluster, we agreed to removed the dir /var/lib/cassandra/ and start the cluster using cassandra 2.0.2.
In order to better understand cassandra, we take a detail look at alter table. But before that, let's create a new keyspace and table.
cqlsh> CREATE KEYSPACE jw_schema1 WITH replication = {'class':'SimpleStrategy', 'replication_factor':3};
cqlsh>and the correspondance cassandra system.log
INFO [Thrift:7] 2013-12-06 16:17:21,902 MigrationManager.java (line 217) Create new Keyspace: jw_schema1, rep strategy:SimpleStrategy{}, strategy_options: {replication_factor=3}, durable_writes: true
