如何设置这个？我有一个复制因子为 3 的三节点集群，在启动时出现以下错误：

WARN [NonPeriodicTasks:1] 2013-10-08 14:06:42,751 PasswordAuthenticator.java (line 242) PasswordAuthenticator skipped default user setup: some nodes were not ready
WARN [NonPeriodicTasks:1] 2013-10-08 14:06:42,763 Auth.java (line 223) Skipped default superuser setup: some nodes were not ready

没有创建默认用户，并且尝试使用例如 cqlsh 登录失败：

$ cqlsh mynode myport -u cassandra -p cassandra
Traceback (most recent call last):
  File "/usr/opt/apache-cassandra-2.0.1/bin/cqlsh", line 2031, in <module>

错误消息“一些节点尚未准备好”有点误导，因为似乎原因是集群中有两个其他节点启动并运行，但配置为仍使用 AllowAllAuthenticator。在关闭其他节点并使用 PasswordAuthentitor 启动一个节点后，创建默认用户成功：

 INFO [NonPeriodicTasks:1] 2013-10-09 14:44:57,028 PasswordAuthenticator.java (line 237) PasswordAuthenticator created default user 'cassandra'
 INFO [NonPeriodicTasks:1] 2013-10-09 14:44:57,760 Auth.java (line 218) Created default superuser 'cassandra'

在我的情况下，这是因为数据中心名称已更改，然后由于 Puppet 而被推广到配置文件 (cassandra-topology.properties)。因此，已为 system_auth 配置的 NetworkTopologyStrategy 失败。

第一次使用这些选项启动节点时，您必须串行更改“身份验证器：”和“授权人：”而不是并行更改。在与上述错误作斗争时，这种方式对我有用。

您还应该检查 conf/cassandra-topology.properties您是否正在使用PropertyFileSnitch. 它应该在所有节点上都相同
