--------------------------------------
{quote}I can't find any reference to a {{zookeeper-env.sh}} in ZK docs - is
there anything you didn't mention that users should do during setup to be sure
this file is read?
{quote}
The start script for ZooKeeper actually tries looking for a
zookeeper_home/conf/zookeeper-env.sh file and picks up variables from there .
But ZK doesn't ship with an empty zookeeper-env.sh file in the conf directory
so one must create the file and then add those env variables . Here is where
the variables are loaded :
[https://github.com/apache/zookeeper/blob/master/bin/zkEnv.sh#L53]
I don't see the same mechanics in the windows script :
[https://github.com/apache/zookeeper/blob/master/bin/zkEnv.cmd] , so maybe we
just tell windows users to load those variables to bin/zkCli.cmd ?

> I had to set up a ZK ensemble the other day for the first time in a while,
> and thought I'd test our docs on the subject while I was at it. I headed over
> to
> https://lucene.apache.org/solr/guide/setting-up-an-external-zookeeper-ensemble.html,
> and...Well, I still haven't gotten back to what I was trying to do, but I
> rewrote the entire page.
> The problem to me is that the page today is mostly a stripped down copy of
> the ZK Getting Started docs: walking through setting up a single ZK instance
> before introducing the idea of an ensemble and going back through the same
> configs again to update them for the ensemble.
> IOW, despite the page being titled "setting up an ensemble", it's mostly
> about not setting up an ensemble. That's at the end of the page, which itself
> focuses a bit heavily on the use case of running an ensemble on a single
> server (so, if you're counting...that's 3 use cases we don't want people to
> use discussed in detail on a page that's supposedly about _not_ doing any of
> those things).
> So, I took all of it and restructured the whole thing to focus primarily on
> the use case we want people to use: running 3 ZK nodes on different machines.
> Running 3 on one machine is still there, but noted in passing with the
> appropriate caveats. I've also added information about choosing to use a
> chroot, which AFAICT was only covered in the section on Taking Solr to
> Production.
