Elasticsearch快照到Azure blob存储-找不到帐户的Azure客户端

Question

我想更新我们上传快照的Azure存储帐户，但我收到以下错误："找不到帐户[null]]的azure客户端"；只有当我更改存储帐户时才会发生这种情况。此新存储帐户位于不同的区域和订阅中。如果还有其他可能有用的细节，请告诉我。

注意：与此主题相同的错误，但我看到它已关闭。我已经仔细检查了我的凭据和存储帐户名，我相信它们是正确的。

请检查引用是否可以缩小问题范围。

• 根据跟踪的错误，似乎缺少存储快照的容器或客户端帐户名(忽略，因为您已经确认是正确的(一定是可能的原因。

• 通过将cloud.azure.storage.default.container参数添加到elasticsearch.yml配置文件中，并使用要存储快照的容器的名称，或者通过传递HTTP请求上的容器选项。

• 或者，如果不是这样，请检查您是否提供了正确配置的帐户名>("｛｛存储帐户名｝｝.bob.core.windows.net"(，并指向群集中具有帐户名的所有节点的密钥。

• 尝试使用不同于key1或key2 的密钥

• 另请检查〔此存储库azure使用情况〕

• 如果所有配置都正确，请检查是否有防火墙或代理阻止访问。

正确跟踪异常。在logging.yml文件中发送以下请求

PUT /_cluster/settings
{
"transient" : {
"logger.cloud.azure.storage" : "TRACE"
}
}
