--------------------------------------

             Summary: Add admin command to display last snapshot information
                 Key: ZOOKEEPER-3392
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3392
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
    Affects Versions: 3.6.0
            Reporter: Brian Nixon


Basic systems to backup ZooKeeper data will maintain snapshot files of the data tree. In order
to understand the health of these systems, they need a way to determine how in or out of date
their files are to the current state in the ensemble.

Add an admin command that exposes the zxid and timestamp of the last saved/restored snapshot
of the server. This will let such a backup system know when it can update and when it is stale.
