【问题描述】:
cassandra 版本:apache-cassandra-2.1.8
我最近配置了 2 节点集群,其中 Authenticator 设置为 PasswordAuthenticator。当其中一个节点关闭时,我无法登录 Cqlsh 并出现以下错误
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 设置为 2,因为我有 2 个节点。
C:\apache-cassandra-2.1.8-bin\apache-cassandra-2.1.8\bin>nodetool status
