Subject [jira] [Created] (CASSANDRA-12505) Authentication failure for new nodes
Date Fri, 19 Aug 2016 13:43:21 GMT
Mike created CASSANDRA-12505:

             Summary: Authentication failure for new nodes
                 Key: CASSANDRA-12505
             Project: Cassandra
          Issue Type: Bug
         Environment: Ubuntu 16.04
            Reporter: Mike
            Priority: Critical

I added new data center with one node to a cluster. The cluster currently has 5 nodes in 3
data centers. I changed the replication factor of system_auth keyspace according to the number
of nodes. I run nodetool repair and rebuild on new nodes, but I cannot login to the new nodes.
cqlsh reports the following error:
Connection error: ('Unable to connect to any servers', {'ip': AuthenticationFailed(u'Failed
to authenticate to ip: code=0100 [Bad credentials] message="Username and/or password are incorrect"',)})

I tried using both the SimpleStrategy and NetworkTopologyStrategy for the system_auth keyspace
without changes. I am still able to login into old nodes. nodetool status reports that every
node owns 100% of the system_auth keyspace. The log file does not show any errors.
