Cassandra: Apache Cassandra-2.1.8Authentication Cassandra problem
Niedawno skonfigurowany klaster 2 węzeł z Authenticator
zestaw do PasswordAuthenticator
. Gdy jeden z węzła jest w dół nie jestem w stanie zalogować się do Cqlsh i dostaje poniżej błędu
Connection error: ('Unable to connect to any servers',
{'192.168.0.45': AuthenticationFailed(u'Failed to authenticate to 192.168.0.45: code=0100 [Bad credentials]
message="org.apache.cassandra.exceptions.UnavailableException: Cannot achieve consistency level QUORUM"',)})
system_auth RF jest ustawiona na 2, jak mam 2 węzłów.

Mam załączeniu Cassandra plików, cassandra.yaml i złożyć cassandra-topology.properties
