java - 为什么 Riak 将 "inavailable channel closed"消息记录为 ERROR

Question

我不是 Riak 专家，但看起来 inavailable channel closed 消息应该是 INFO 级别，而不是 ERROR 级别的日志消息。当我们的服务器启动以获取用户数据时，我们打开一些 Riak 连接，然后它们超时(这应该没问题，对吧？)，当它们超时时显示 inavailable channel closed 消息。

我们是否错误地使用了 Riak？有真正的错误吗？或者这应该只是一个 INFO 级别，因为它是正常 Riak 生命周期的一部分？

看起来开发人员注意到了同样的事情，因为 this bug去年6月提交，消息在this PR中降为INFO级别一个月后。

如果您仍然将它们视为错误，请将您的 java-riak-client 更新为 v2.0.7或以后。
