如何摆脱卡桑德拉日志中的以下信息？

Question

我最近将datastax-enterprise从4.8.16升级到5.0.15。我们正在使用PlainText格式的密码身份验证。但是下面的消息不断地出现在日志中。

如何摆脱这条消息，因为我现在不感兴趣使用加密？

Answer 1

你需要设置：

authentication_options:
    plain_text_without_ssl: allow

在dse.yaml配置文件中。这方面的可能设置如下：

block  - block the request with an authentication error
warn   - log a warning about the request but allow it to continue (default)
allow  - allow the request without any warning
