Most likely there's something wrong with network configuration: localhost resolves either to invalid hostname assigned by DHCP (something like 192-168-1-10.local) or to local IPv6 address (::1) and IPv6 is disabled in java.

• Check /etc/hosts
• Check output of hostname command
• Try setting listen_address to 127.0.0.1 or to valid IP address.
• Check rpc_address setting in cassandra.yaml. Try setting it to 127.0.0.1
