Subject Re: Can't connect to Cassandra server
Date Mon, 20 Jul 2015 01:08:25 GMT
Hello, Chamila.

>From the information you have supplied so far, it is not clear whether
Cassandra is in fact running.

Please provide the output of the following:

$ netstat -a -n | grep LISTEN
$ sudo lsof -i -n | grep LISTEN | grep java


It would also be good if you could provide output.log

Cheers,
Erick
