[0001]Resource lookup fail 线程池超时优化

# 一、问题现象与触发条件

# 1、页面报错现象

在 Ranger 中配置 Resource（例如 Hive 的 database/table）时，如果输入节奏较快，页面会弹出类似提示：

Resource lookup fail for current resource

image-20260116210156350

现象特征

  • 慢慢输入通常正常
  • 连续快速输入（触发多次联想/下拉请求）更容易复现
  • UI 侧看起来像“偶发”，日志侧通常会稳定出现 TimeoutException

# 2、典型复现场景

  • 集群启用了 Kerberos
  • Ranger 在做 Hive 资源联想时依赖 Hive JDBC（含 ZK serviceDiscovery）
  • ZooKeeper / HiveServer2 存在轻微抖动或瞬时并发偏高
  • Ranger Admin 侧 TimedExecutor 线程池较小，导致任务排队明显

# 二、日志定位：lookupResource TimeoutException

# 1、核心报错解读

日志里关键点主要是两行：

  • lookupResource(...) failed
  • java.util.concurrent.TimeoutException

意味着：Ranger Admin 在规定时间内没有拿到 lookup 的结果（可能是任务本身慢，也可能是排队时间过长导致“还没执行就超时”）。

# 三、根因分析：TimedExecutor 排队 + Hive/ZK 链路耗时

# 1、调用链路一眼看懂

从堆栈可以直接定位到关键链路：

  • ServiceREST.lookupResource(...)
  • ServiceMgr.lookupResource(...)
  • TimedExecutor.timedTask(...)
  • FutureTask.get(...) → 超时抛出 TimeoutException

结论

这个问题不是“UI 输入框本身坏了”，而是 Ranger Admin 的 lookup 任务在超时窗口内没有返回。 超时可能来自两类叠加：下游慢 + 任务排队。

# 2、为什么“输快了就炸”

快速输入会触发高频 lookup 请求，Ranger Admin 同时要做的事情通常包括：

触发项 发生了什么 影响点
高频请求 UI 每次输入变更都会触发联想 并发瞬时拉高
TimedExecutor 线程池偏小 lookup/validate 等任务需要线程执行 队列排队时间变长
Hive JDBC + ZK serviceDiscovery 需要读取 /hiveserver2 namespace 并建立连接 链路一抖动就变慢
Kerberos 链路开销 认证、票据、服务端响应慢时更明显 容易顶到超时上限

风险提醒

  • 线程池盲目拉大，会把并发压力“原样”推到 HiveServer2/ZK
  • 正确做法通常是：适度增大线程池 + 提高超时窗口，再结合 HS2 承载能力观察效果

# 四、优化方案一：在 Ambari Stack 暴露参数（源码级改造）

# 1、修改文件路径

新增配置项（Ambari Stack）：

ambari-server/src/main/resources/stacks/BIGTOP/3.2.0/services/RANGER/configuration/ranger-admin-site.xml

处理办法可参考

>>>>>>线程池与超时参数调优

# 3、重启与验证

配置保存后，重启 Ranger，再回到页面快速输入资源名验证：

image-20260119085944390

验证要点

  • UI 不再弹出 “Resource lookup fail for current resource”
  • ranger-admin 日志中 lookupResource(...) failed + TimeoutException 明显减少或消失
#Ranger#Ranger Admin#Resource Lookup#lookupResource#TimeoutException#TimedExecutor#HiveServer2#ZooKeeper#Ambari#ranger-admin-site
[0002]>>>>>日期统一规则调优
[0001]>>>>>>线程池与超时参数调优
