kuaikuai opened a new pull request #3782: Update EtcdCoordinator.java
URL: https://github.com/apache/skywalking/pull/3782
 
 
   - Why submit this pull request?
   
   when EtcdCoordinator cannot connect to etcd cluster for a long time, 
   the information registered in etcd will expire and refresh() function will not work.
   
   - How to fix?
   When refresh() finds that the key does not exist, an exception is thrown, and we catch the exception to rewrite the registration information.
