Can not connect to cassandra 0.7 using CLI
Hi there,
I just downloaded cassandra 0.7rc1. I started it using bin/cassandra without
making any configuration changes.
I then tried to connect using the CLI with command like this:
foo@ubuntu:~/Applications/apache-cassandra-0.7.0-rc1$ bin/cassandra-cli
Welcome to cassandra CLI.
Type 'help' or '?' for help. Type 'quit' or 'exit' to quit.
[default@unknown] connect localhost/9160;
Exception connecting to localhost/9160. Reason: Connection refused.
Why am I getting connection refused? I didn't experience this with cassandra
0.6.8.
Thank you in advance for your help.
Kind regards,
Joshua.

thanks a lot for help! I don't know what exactly was wrong (because I deleted
everything including java and started from the very beginning) but now
everything seems to work perfectly and I'm doing first stepes with Cassandra.
By the way...
Maybe do you have some useful advices (or you know some articles) about making
working the "ring". I want to make databases under control of Cassandra which
will consist of a few computers working together. (?)
thanks for help
best regards

Make sure that the directory /var/log/cassandra exists and the user running cassandra has permission to use it.
There are some instructions here in the readme file
https://github.com/apache/cassandra/blob/cassandra-0.7.9/README.txt#L27
Good luck.

I've got the same problem :( I've tried "netstat -nl | grep 9160"
and received nothing on the console output. In my cassandra.yaml
file I've got:
listen_address: localhost
rpc_address: localhost
rpc_port: 9160
rpc_keepalive: true
(it might be a clue what is wrong) when I type "cassandra" on
the terminal I get this:
julio@julio-System-Product-Name:~$ log4j:ERROR setFile
(null,true)
call failed.
java.io.FileNotFoundException: /var/log/cassandra/system.log
(Permission denied)
at java.io.FileOutputStream.openAppend(Native Method)
at java.io.FileOutputStream.<init>
(FileOutputStream.java:207)
and more ... ;/
what should I do? maybe I make silly mistakes but I'm completely
new to noSQL and Cassandra. Please, help me!
best regards
Julio

Hi Eric,
Thanks for the hint. I have found out that if there is an exception thrown,
the thrift server won't be started. It is working fine now.
Kind regards,
joshua.

Try "netstat -nl | grep 9160". Is the node listening on 9160? Which
interface is it bound to?

It is set to localhost I didn't change it and it is the same as configured
in 0.6.8. Why doesn't it work out of the box?
Thanks heaps.

Take a look at your cassandra.yaml file at the rpc_address this is the address it's listening to connections on. The comments there should help, if you set it to 0.0.0.0 it will bind to all interfaces. Probably not what you want in production but handy for dev.
Hope that helps.

All of the times I have had similar issues the problem has always been misconfigured iptables. You said it was running fine on 0.6.8 though?
On the same box or a different box?
