sijie opened a new pull request #1338: Fallback to use `getZkServers` and `getZkLedgersPath` when resolving from metadata service uri
URL: https://github.com/apache/bookkeeper/pull/1338
 
 
   Descriptions of the changes in this PR:
   
   *Problme*
   
   Dlog tests are failing because dlog is using an external zookeeper client, where both `zkServers` and `metadataServiceUri`
   are not set on client configuration. It will throw NPE when trying to resolve `zkServers` and `zkLedgersRootPath` from metadata service uri.
   
   *Solution*
   
   Fallback to use deprecated `getZkServers` and `getZkLedgersPath` when metadata service uri is null
