ZooKeeper is a very low level system that requires users to do a lot of housekeeping. See:
-* https://wiki.apache.org/hadoop/ZooKeeper/FAQ
+* https://cwiki.apache.org/confluence/display/ZOOKEEPER/FAQ
The Curator [Framework](framework.md) is designed to hide as much of the details/tedium of this housekeeping as is possible.

| LOST | Curator will set the LOST state when it believes that the ZooKeeper session has expired. ZooKeeper connections have a session. When the session expires, clients must take appropriate action. In Curator, this is complicated by the fact that Curator internally manages the ZooKeeper connection.

## Details
-ZooKeeper's clients maintain a session with the server ensemble. Ephemeral nodes are tied to this session. When writing ZooKeeper-based applications you must deal with session expirations (due to network partitions, server crashes, etc.). This ZooKeeper FAQ discusses it: http://wiki.apache.org/hadoop/ZooKeeper/FAQ#A3

For the most part, Curator shields you from the details of session management. However, Curator's behavior can be modified. By default, Curator treats session failures the same way that it treats connection failures: i.e. the current retry policy is checked and, if permitted, operations are retried.
