Hi Jonathan,
Thanks for the fast reply.

Right. The only thing you that should be different is the
ListenAddress section. (You can try leaving that out and Cassandra
will pick an interface to use but it often guesses a non-public
interface which is not helpful. :)
Changed to public interface, now it shows all the nodes.
:)
3.2 finally: should I start a cluster with an empty DB or I can
replicate an
existing DB?
You can start from an existing one if it's really legitimate for all
nodes to have copies of that data but it probably is not.
Ok, since each node had the same token (and sounded quite strange), I
emptied the /var/cassandra folder.
Restarting the service, each node took a different token.
Was it correct?
Now a strange thing (please be patient, I'm a newbie):
Inserted a set of pairs (data,key) running "cassandra-cli" from host
10.0.1.1
Then:
./bin/cassandra-cli --host 10.0.1.2
cassandra> get Table1.Standard1['foo']
COLUMN_TIMESTAMP = 1241219309914; COLUMN_VALUE = data; COLUMN_KEY = bar;
COLUMN_TIMESTAMP = 1241218702595; COLUMN_VALUE = data2; COLUMN_KEY =
bar2;
COLUMN_TIMESTAMP = 1241211956945; COLUMN_VALUE = data3; COLUMN_KEY =
bar3;
then:
./bin/cassandra-cli --host 10.0.1.3
cassandra> get Table1.Standard1['foo']
COLUMN_TIMESTAMP = 1241219309914; COLUMN_VALUE = data; COLUMN_KEY = bar;
COLUMN_TIMESTAMP = 1241218702595; COLUMN_VALUE = data2; COLUMN_KEY =
bar2;
COLUMN_TIMESTAMP = 1241211956945; COLUMN_VALUE = data3; COLUMN_KEY =
bar3;
Ok, it's GREAT (I'm querying the cluster from different servers, right?)
If I try the same via web interface, it works only on nodes 10.0.1.1
and 10.0.1.3.
"Success: Key = foo
...
"
on 10.0.1.2: "Error: Key [foo], column family [Standard1] not found."
Any idea?
I also submit a couple of errors that raised using the command-line
client:
Okay, so the problems are that (1) it thinks it is connected when it
is not, and (2) it allows you to run commands when it is not
connected. Right?
Not exactly.
"show config file" causes the client disconnection from each of the
nodes.
I'll take a look into the issue tracker.
Can you file those in the issue tracker?
