Not able to cqlsh on 2.1.9 on Ubuntu 14.04
Hi All.
We have setup a Ubuntu-14.04 server, and followed the steps exactly as
per http://wiki.apache.org/cassandra/DebianPackaging
Installation completes fine, Cassandra starts fine, however cqlsh does not work.
We get the error ::
#######################################################################################################
ajay@comp:~$ cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1':
error(None, "Tried connecting to [('127.0.0.1', 9042)]. Last error:

Any ideas please?? We have been stuck on this for a good 3 hours now :(
Thanks and Regards,

Hi All.
I re-established my server from scratch, and installed the 21x server.
Now, cqlsh works right out of the box.
When I had last setup the server, I had (accidentally) installed the
20x server on first attempt, removed it, and then installed the 21x
series server. Seems that caused some hidden problem.
I am heartfully grateful to everyone for bearing with me.
Thanks and Regards,
Ajay

Hi Jared.
Thanks for your help.
I made the config-changes.
Also, I changed the seed (right now, we are just trying to get one
instance up and running) ::
################################################################
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "our.ip.address.here"
################################################################
Following is the netstat output ::
################################################################
ajay@comp:~$ sudo netstat -apn | grep 9042
tcp6 0 0 0.0.0.0:9042 :::*
LISTEN 22469/java
################################################################
Still, when I try, we get ::
################################################################
ajay@comp:~$ cqlsh our.ip.address.here
Connection error: ('Unable to connect to any servers',
{'our.ip.address.here': error(None, "Tried connecting to
[('our.ip.address.here', 9042)]. Last error: None")})

Re: Not able to cqlsh on 2.1.9 on Ubuntu 14.04
Posted by Jared Biel <ja...@bolderthinking.com>.
Is there a reason that you're setting listen_address and rpc_address to
localhost?
listen_address doc: "the Right Thing is to use the address associated with
the hostname". So, set the IP address of this to eth0 for example. I
believe if it is set to localhost then you won't be able to form a cluster
with other nodes.
rpc_address: this is the address to which clients will connect. I recommend
0.0.0.0 here so clients can connect to IP address of the server as well as
localhost if they happen to reside on the same instance.
Here are all of the address settings from our config file. 192.168.1.10 is
the IP address of eth0 and broadcast_address is commented out.
listen_address: 192.168.1.10
# broadcast_address: 1.2.3.4
rpc_address: 0.0.0.0
broadcast_rpc_address: 192.168.1.10
Follow these directions to get up and running with the first node
(destructive process):
1. Stop cassandra
2. Remove data from cassandra var directory (rm -rf /var/lib/cassandra/*)
3. Make above changes to config file. Also set seeds to the eth0 IP address
4. Start cassandra
5. Set seeds in config file back to "" after cassandra is up and running.
After following that process, you'll be able to connect to the node from
any host that can reach Cassandra's ports on that node ("cqlsh" command
will work.) To join more nodes to the cluster, follow the steps same steps
as above, except the seeds value to the IP address of an already running
node.
Regarding the empty "seeds" config entry: our configs are automated with
configuration management. During the node bootstrap process a script
performs the above. The reason that we set seeds back to empty is that we
don't want nodes coming up/down to cause the config file to change and thus
cassandra to restart needlessly. So far we haven't had any issues with
seeds being set to empty after a node has joined the cluster, but this may
not be the recommended way of doing things.

Re: Not able to cqlsh on 2.1.9 on Ubuntu 14.04
Posted by Ajay Garg <aj...@gmail.com>.
Hi All.
Thanks for your replies.
a)
cqlsh <IP-Address of server> does not work either :(
b)
Following are the parameters as asked ::
listen_address: localhost
rpc_address: localhost
broadcast_rpc_address is not set.
According to the yaml file ::
# RPC address to broadcast to drivers and other Cassandra nodes. This cannot
# be set to 0.0.0.0. If left blank, this will be set to the value of
# rpc_address. If rpc_address is set to 0.0.0.0, broadcast_rpc_address must
# be set.
# broadcast_rpc_address: 1.2.3.4
c)
Following is the netstat-output, with process information ::
#######################################################################################################
ajay@comp:~$ sudo netstat -apn | grep 9042
[sudo] password for admin:
tcp6 0 0 127.0.0.1:9042 :::*
LISTEN 10169/java
#######################################################################################################
Kindly let me know what else we can try .. it is really driving us nuttsss :(

Whoops, I accidentally pressed a hotkey and sent my message prematurely.
Here's what netstat should look like with those settings:
sudo netstat -apn | grep 9042
tcp6 0 0 0.0.0.0:9042 :::* LISTEN
21248/java

I assume "@ Of node" is ethX's IP address? Has cassandra been restarted
since changes were made to cassandra.yaml? The netstat output that you
posted doesn't look right; we use settings similar to what you've posted.
Here's what it looks like on one of our nodes.
