I am trying to connect to cassandra. I installed the latest stable version that is apache-cassandra-1.2.4 and extracted it on my desktop. As I run cassandra it sets up nicely listening for thrift client and displaying following :

sudo cassandra -f

log :

Now as I run : cassandra-cli -h localhost -p 9160, it throws up the error. I have checked for the port to be free and cassandra is listening at the port. :

    Your log says 'Cassandra version: 1.0.12'. Have you upgraded from a previous version? Are you sure Cassandra started? Is it showing in ps and netstat output? Is there anything in cassandra.log (as opposed to the system.log output you posted)? – Richard Apr 14 '13 at 20:41

    Try `cassandra-cli -h 127.0.0.1 -p 9160` instead of localhost. It should mean the same thing, depending on your hosts file, but can be a good troubleshooting step. – phatfingers Apr 15 '13 at 02:52
  • Solved the issue - Cassandra service was not running on and therefore causing the cassandra cli to shutdown. Thanks! – user1795516 Apr 28 '13 at 20:05

I had the same error.Now, it is OK.

The main problem is that the configuration is wrong.

My configuration is as following:

My visual machine ip is 192.168.11.11.My cassandra was installed into the machine.So, I configurate thar 

listen_address: 192.168.11.11
rpc_address: 0.0.0.0
broadcast_rpc_address: 192.168.11.11

That is OK。

The documentation of cassandra-stress seems to be sketchy. Maybe in due course that would be corrected. As of now, this command worked for me

./cassandra-stress write -node <IP_OF_NODE1>

Once this works, we could try putting in the other optional parameters to tweak our command.

Option 1:

Run jps command under root user and kill CassandraDaemon if you will see it. After this you will start Cassandra again.

Option2: 

Try to connect Cassandra with CQL 
  ./cqlsh 10.234.31.232 9042

Final Check:

An intermediate firewall is blocking the JVM from making the connection. 
An operating system firewall, or antivirus that is causing the problems as well.

I think you installed in windows and looks like firewall is blocking your connection.
