Hi all,
Sorry if this is a fairly stupid question, but we've all only been exposed
to Cassandra very recently.
We're trying to configure a 2-node cluster with non-default credentials.
Here's what I've been doing so far based on my understanding of the
documentation. The platform is RHEL 7:
1. Use an RPM I found with Datastax to perform a basic cassandra
installation.
2. Change the temporary directory in cassandra-env.sh, because nobody is
allowed to execute anything in /tmp.
3. In cassandra.yaml,
- change the cluster_name
- empty the listen_address entry
- define both VMs as seeds
4. Open port 7000 in the firewall.
5. Start cassandra.
6. In the cassandra.yaml, change to PasswordAuthenticator.
7. Run cqlsh -u cassandra -p cassandra -e "ALTER KEYSPACE system_auth
WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 2
};"
8. Restart cassandra
9. Perform 1-8 on the second node
10. To create a new user, run cqlsh -u cassandra -p cassandra -e "CREATE
USER ${CASSANDRA_USERNAME} WITH PASSWORD '${CASSANDRA_PASSWORD}' SUPERUSER;"
Step 10 fails with this error:
Connection error: ('Unable to connect to any servers', {'127.0.0.1':
AuthenticationFailed(u'Failed to authenticate to 127.0.0.1: code=0100 [Bad
credentials] message="org.apache.cassandra.exceptions.UnavailableException:
Cannot achieve consistency level QUORUM"',)})
What am I missing?
Cheers
Raimund
