如何摆脱 cassandra 日志中的以下消息？

Question

我最近将 datastax-enterprise 从 4.8.16 升级到 5.0.15。我们使用纯文本格式的密码身份验证。但日志中不断出现以下消息。

2018-12-11 09:50:04.446 WARN   [SharedPool-Worker-5 - com.datastax.bdp.cassandra.auth.DseAuthenticator:411] Plain text authentication without client / server encryption is strongly discouraged

由于我现在对使用加密不感兴趣，如何摆脱此消息？

Answer 1

您需要设置：

authentication_options:
    plain_text_without_ssl: allow

在你的dse.yaml配置文件中。可能的设置是：

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
