一、问题现象与触发点
1、页面报错
页面级别报错信息（核心关键词：KnoxUrl / topologies）：
Error! org.apache.ranger.plugin.client.HadoopException: Exception on REST call to
KnoxUrl : https://dev1:6543/gateway/admin/api/v1/topologies.
这个报错通常出现在哪里？
常见于 Ranger Admin → Service → Knox Service → Resource Lookup（例如选择 topology / service / path 时的下拉与联想查询），Ranger
会定时或按需调用 Knox Admin API 拉取拓扑列表。
2、后台日志（关键链路）
bash

这类
trustAnchors must be non-empty基本可以直接归到一类：JVM 在 TLS 握手时加载到的 trustStore 为空 / 未配置 /
指向了错误文件 / 文件不可读，导致 PKIX 校验初始化失败。
这是报错截图：
二、根因拆解：为什么是 trustAnchors must be non-empty
1、异常来自哪里
异常栈里最关键的一段是：
PKIXValidator.<init>PKIXParameters.setTrustAnchorsInvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
这句话翻译成人话
做证书链验证时，信任根证书列表是空的。换句话说：要么 trustStore 没有任何条目，要么 Ranger 进程根本没加载到该 trustStore。
2、为什么会在 Knox Topologies 请求上触发
Ranger Knox 插件在拉取资源（topologies）时走 HTTPS：
- 目标地址：
https://dev1:6543/gateway/admin/api/v1/topologies - 客户端：Ranger Admin（
org.apache.ranger.services.knox.client.KnoxClient）
只要 Knox 使用了自签或内网 CA，而 Ranger JVM 没把对应证书链加入信任库，就会在握手阶段失败。
一个很容易踩到的点
即使已经生成了
ranger-admin-truststore.jks，如果启动参数里没有带-Djavax.net.ssl.trustStore=...，效果等价于"没有配置"。
三、解决方案：导入 Knox 证书到 Ranger trustStore
::: danger 处理办法可参考
22206:解决办法
:::
六、验证结果：topologies 可访问 + Knox 权限联动正常
1、Ranger 侧 Resource Lookup 恢复
2、策略验证：只允许访问 HDFS，其它全部拒绝
当配置为"只能访问 hdfs"后，其它就访问不了了：
被拒绝时，日志会显示拒绝记录：
这一步的意义
证书问题解决后，Ranger ↔ Knox 的联动就回到"正常的权限治理问题"，后续只需要按策略与审计来验证访问边界即可。
