Deprecated Classes

Class and Description
org.apache.curator.framework.recipes.locks.ChildReaper Since 2.9.0 - Reaper/ChildReaper are no longer needed. Use CreateMode.CONTAINER. Also, all Curator recipes create container parents.
org.apache.curator.framework.recipes.locks.InterProcessSemaphore Use InterProcessSemaphoreV2 instead of this class. It uses a better algorithm.
org.apache.curator.framework.recipes.nodes.PersistentEphemeralNode This has been replaced with the more general PersistentNode
org.apache.curator.framework.recipes.locks.Reaper Since 2.9.0 - Reaper/ChildReaper are no longer needed. Use CreateMode.CONTAINER. Also, all Curator recipes create container parents.

Deprecated Enums

Enum and Description
org.apache.curator.framework.recipes.cache.PathChildrenCacheMode no longer used. Instead use either PathChildrenCache.PathChildrenCache(CuratorFramework, String, boolean) or PathChildrenCache.PathChildrenCache(CuratorFramework, String, boolean, ThreadFactory)
org.apache.curator.framework.recipes.nodes.PersistentEphemeralNode.Mode This has been replaced with the more general PersistentNode

Deprecated Methods

Method and Description
org.apache.curator.framework.recipes.cache.PathChildrenCache.start(boolean) use PathChildrenCache.start(StartMode)
org.apache.curator.framework.recipes.shared.SharedCount.trySetCount(int) use trySetCount(VersionedValue, int) for stronger atomicity guarantees. Even if this object's internal state is up-to-date, the caller has no way to ensure that they've read the most recently seen count.
org.apache.curator.framework.recipes.shared.SharedValue.trySetValue(byte[]) use SharedValue.trySetValue(VersionedValue, byte[]) for stronger atomicity guarantees. Even if this object's internal state is up-to-date, the caller has no way to ensure that they've read the most recently seen value.

Deprecated Constructors

Constructor and Description
org.apache.curator.framework.recipes.leader.LeaderSelector(CuratorFramework, String, ThreadFactory, Executor, LeaderSelectorListener) This constructor was poorly thought out. Custom executor is useless. Use this version instead: LeaderSelector.LeaderSelector(CuratorFramework, String, ExecutorService, LeaderSelectorListener)
org.apache.curator.framework.recipes.cache.PathChildrenCache(CuratorFramework, String, PathChildrenCacheMode) use PathChildrenCache.PathChildrenCache(CuratorFramework, String, boolean) instead
org.apache.curator.framework.recipes.cache.PathChildrenCache(CuratorFramework, String, PathChildrenCacheMode, ThreadFactory) use PathChildrenCache.PathChildrenCache(CuratorFramework, String, boolean, ThreadFactory) instead
