We don't have dynamic configuration yet, but it is on our todo list: http://wiki.apache.org/hadoop/ZooKeeper/ClusterMembershipso for now I believe you would have to reconfigure manually and restart the cluster. For Zab, you should be looking at org.apache.zookeeper.server.quorum.Cheers,-FlavioOn

This isn't as efficient as it can be though if you're doing it
frequently (which we don't do), but it works for us.

You probably want to do a rolling restart, this is preferable over
restart the cluster as the service will not go down.

Simplified: when a server comes back up it checks it's local snaps/logs to
reconstruct as much of the current state as possible. It then checks with
the leader to see how far behind it is, at which point it either gets a diff
or gets a full snapshot (from the leader) depending on how far behind it
Vishal, this sounds like a bug in ZK to me. Can you create a JIRA with this
description, your configuration files from all servers, and the log files
from all servers during the time of the incident? If you could run the
servers in DEBUG level logging during the time you reproduce the issue that
Restart all clients too.

1. it is still in prototype phase. we are evaluating different aspects,
but there is still some work to do to make it production ready. we also
need to
