             Summary: YarnRegistryViewForProviders#deleteChildren() should 
handle the case where path doesn't exist
                 Key: SLIDER-495
                 URL: https://issues.apache.org/jira/browse/SLIDER-495
             Project: Slider
          Issue Type: Bug
            Reporter: Ted Yu
            Assignee: Ted Yu
            Priority: Minor


When registryOperations.list() throws PathNotFoundException, the for loop would 
try to iterate through childNames which is null.

We should return in case PathNotFoundException is thrown.
