通过doris-operator进行修改fe 或者be replicas的数量 只能增加 不能减少 减少无效 这个是正常的吗?

通过doris-operator进行修改fe 或者be replicas的数量 只能增加 不能减少 减少无效 这个是正常的吗?

[617450941]

我的配置如下 修改replicas只能往上加 减少是没有任何变化的 减少操作的时候doris-operator的容器里面还会报错误

Thank you for your feedback, this is a valuable issue, I have fixed it #207 . If you are in a hurry to use the fe scaling function, you can configure electionNumber: 3 in feSpec (3 is the default value, which means the number of fe followers) to avoid this problem.
感谢你的反馈，这是一个很有价值的问题，我已经修复了他。 如果你着急使用缩容fe 功能， 可以在 feSpec 内配置 electionNumber: 3 (3是默认值，意味着fe follower 的数量)，就能避免这个问题。
