dubbo使用元数据中心，zookeeper地址如果太长，会报错Failed to save service store file

[yeeeee7]

dubbo:3.2.0版本 zookeeper地址使用k8s headless地址：data-zookeeper-0.zookeepers.platform.svc.cluster.local:2181,data-zookeeper- 1.zookeepers.platform.svc.cluster.local:2181,data-zookeeper-2.zookeepers.platform.svc.cluster.local:2181

@aamingaa PTAL

[aamingaa]

前缀太长了，windows会把地址前缀也算进去

[yeeeee7]

如何解决？是linux报错，不是windows @aamingaa

@yeeeee7 不太严格的说 在k8s 中xxx.svc.cluster.local 和xxx 是相同的 其实你可以直接去掉svc.cluster.local 后缀
