1 前言

一个问题，一篇文章，一出故事。
今天在cmak中添加集群（Add Cluster）出现如下错误提示。

Yikes! Ask timed out on [ActorSelection[Anchor(akka://kafka-manager-system/), Path(/user/kafka-manager)]] after [5000 ms]. Message of type [kafka.manager.model.ActorModel$KMAddCluster]. A typical reason for `AskTimeoutException` is that the recipient actor didn't send a reply. Try again.
Yikes! Failed to acquire lock for kafka manager command Try again.

本章将整理该错误的解决方法。

2 最佳实践

2.1 测试环境

如何部署Oracle Linux 10.x CMAK？

2.2 在zookeeper服务器上查找错误

tail -f /var/log/zookeeper/zookeeper.out

发现有如下错误，

2026-03-19 13:53:08,704 [myid:3] - INFO  [ProcessThread(sid:3 cport:-1)::PrepRequestProcessor@627] - Got user-level KeeperException when processing sessionid:0xff9ce5c6a7b00026 type:create cxid:0x1d zxid:0x2000005d0 txntype:-1 reqpath:n/a Error Path:/kafka-manager/mutex/locks Error:KeeperErrorCode = NoNode for /kafka-manager/mutex/locks
2026-03-19 13:58:07,675 [myid:3] - INFO  [ProcessThread(sid:3 cport:-1)::PrepRequestProcessor@627] - Got user-level KeeperException when processing sessionid:0xff9ce5c6a7b00026 type:create cxid:0x178 zxid:0x2000005eb txntype:-1 reqpath:n/a Error Path:/kafka-manager/mutex/leases Error:KeeperErrorCode = NoNode for /kafka-manager/mutex/leases

注：提示读取zookeeper的两个路径“/kafka-manager/mutex/locks”和“/kafka-manager/mutex/leases”时报错，原因是路径不存在。

2.3 修复方案

zookeeper-client -server hd01.cmdschool.org

执行如下命令，

create /kafka-manager ""
create /kafka-manager/mutex ""
create /kafka-manager/mutex/locks ""
create /kafka-manager/mutex/leases ""
