Apologies for the late notice, but I wanted to advertise a pair of short
talks by Mahadev and myself at the Hadoop Meetup tonight in Oakland:
Mahadev will be giving a broad overview of ZooKeeper and talking about its
uses inside and outside of Yahoo!, and I will be talking about upcoming
features
FYI - in Ted's scenario your application will most likely not be
effected (if that's what you mean by "start a round of consensus").
From your app's perspective your ZK clients will get disconnected from
one server and reconnected to another (as the server it is connected to
is restarted with
Ah. Sorry. But I got it. I guess what Henry is working on is what I am
looking for.
Thanks

You have two options.
What Henry is talking about is a sophisticated update to ZK internals that
does a very nice job of handling all the possible split-brain issues and
other pathologies that can result from growing or shrinking a cluster. His
patch isn't ready yet, but when it is, it should be
I would prefer not restarting. Start/Stop the new/old process and then start
a round of consensus for adding/removing a machine. I guess if one can do
that then there is stopping of process required. Am I missing something
here?

It is pretty easy to do by hand and is pretty easy to script (it was for
us).
The process for adding is
a) configure and start a new node
b) re-configure and restart each existing node in turn to know about the new
node
you now have a larger cluster.
To drop a node,
a) reconfigure and restart
Hi -
Yes there are future plans. See
https://issues.apache.org/jira/browse/ZOOKEEPER-107. I have code written for
this that works but is not rock-solid yet.

Hi All
Is it possible to remove nodes and add nodes dynamically to the ZK cluster
via API? Any plans in the future to do this?
TIA
