Which one is undefined. then searched for StackOverflow, a vulnerability on Mac Java7, and then replaced Java8, unifying the JRE and JDK versions to 1.8.0 update 25 above. The result is still the same. then, I just transfer the reason to the last malformedurlexception, I see the hosts, found completely normal, really can't son, and today to another Mac installed the same version of Java, Start Cassandra, completely normal, except that my own Mac. stumbled upon a method, see the URL link in Appendix: , using the scutils-get HostName command to view the current HostName, altogether is empty. Then use scutils -set HostName localhost , then restart Cassandra, completely normal. reference: "1": http://biomedicalontologies.com/2012/11/14/fixing-java-net-local-host-name-unknown-error-on-mac-os-x/
