[GitHub] [helix] narendly commented on issue #895: Update listClusters() in ZkHelixAdmin

narendly commented on issue #895: Update listClusters() in ZkHelixAdmin
URL: https://github.com/apache/helix/pull/895#issuecomment-598982274
 
 
   This PR is ready to be merged, approved by @pkuwm 
   
   This PR updates getClusters() in ZkHelixAdmin in realm-aware mode. It is difficult to reason about getting all clusters - and this method, on single-realm mode, is also broken anyways because in the case users create nested clusters, this method will end up returning nothing. This update is backward-compatible for single-realm users.
   
   Ideally, users should use Metadata Store Directory Service to get the list of all clusters.
