--------------------------------------
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determine how in or out of date their files are to the current state in the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.
