   @menghaoranss 
   I'm sorry to raise such an issue... I found that I couldn't reproduce this 
operation in `server-lists` on another machine, and the error in `input string` 
was also prompted. I realized that it might be because of the old machine,the 
`volumes` was not cleaned up, which caused him to connect to `zookeeper` 
normally. In fact, the encapsulation of `curator` by `shardingsphere` does not 
support writing parameters in `zookeeper url`, which is my problem. I will 
close this issue .
