1.In the cassandra.yaml, comment out the default AllowAllAuthorizer and add the CassandraAuthorizer as shown
here:
#authorizer: org.apache.cassandra.auth.AllowAllAuthorizer
authorizer: org.apache.cassandra.auth.CassandraAuthorizer


and restart -> now you can access to cassandra 

cassandra-cli -u cassandra -pw cassandra
