【问题描述】：

当我使用 version 5.2.X 执行 datastax-agent 时，出现以下错误：

但是我没有找到可以放 cassandra 的用户名和密码的地方？任何建议将不胜感激！

【问题讨论】：

您能否在代理节点上包含 address.yaml 以及来自 opscenterd 服务器的 {clusterid}.conf？还有那个节点上的 rpc_address 是什么 cassandra.yaml

标签： datastax opscenter

【解决方案1】：

您可以尝试在您的 address.yaml 配置文件中手动配置凭据。

cassandra_user： cassandra_pass：
