             Summary: Discovery sample did not check for exceptions
                 Key: CURATOR-585
                 URL: https://issues.apache.org/jira/browse/CURATOR-585
             Project: Apache Curator
          Issue Type: Bug
    Affects Versions: 5.1.0
         Environment: MacBook Pro (15-inch, 2019)

            Reporter: 王杰
            Assignee: Jordan Zimmerman
             Fix For: awaiting-response


I tried to run `DiscoveryExample` to simulate service discovery, when I first 
entered list to see the list of registrations, I found that the process exited 
directly, I checked the code and found that the code threw `NoNodeException` 
but it was ignored.

I think if there is no service registered, using `list` should tell me that no 
service is registered instead of just ignoring the exception and closing the 
connection, so I am asking this question, what do you think?
