Curator 5.0 Breaking Changes​

Curator 5.0 contains a few non-backward compatible/breaking changes from previous versions.

  • ZooKeeper 3.4.x is no longer supported (the associated Compatibility classes/methods have been removed). If you still need to use Curator with ZooKeeper 3.4.x you will need to use a previous version. Click here for details.
  • The old ListenerContainer classes have been removed so as not to leak Guava classes into Curator APIs. Instead, use the new StandardListenerManager.
  • Exhibitor support has been removed.
  • ConnectionHandlingPolicy and related classes have been removed.
  • The Reaper and ChildReaper classes/recipes have been removed. You should use ZooKeeper container nodes instead.
  • newPersistentEphemeralNode() and newPathChildrenCache() were removed from GroupMember.
  • ServiceCacheBuilder<T> executorService(CloseableExecutorService executorService) was removed from ServiceCacheBuilder.
  • ServiceProviderBuilder<T> executorService(CloseableExecutorService executorService) was removed from ServiceProviderBuilder.
  • static boolean shouldRetry(int rc) was removed from RetryLoop.
  • static boolean isRetryException(Throwable exception) was removed from RetryLoop.
