Apache Dubbo Component

Java SDK (apache/dubbo)

Details

Background：
our dubbo client and zk deploy in k8s，but not at the same k8s。 the zk cluster use Headless service as zk server address，expose loaderbalancer ip for dubbo client use。

When the Dubbo client reconnects to Zookeeper, the reconnection fails because it cannot resolve the headless domain name.

The reasons is：

1、curator in 3.0.0 version add EnsembleTracker, when zk client start ,will get /zookeeper/config znode data ,and change user defined zk IP address, at this time ,the ip changed to headless domain。

so ,how can i close the curator curator EnsembleTracker in dubbo ?

While the new version releases. you can disable EnsembleTracker by config.

dubbo:
