Varun Thacker commented on SOLR-12163:
--------------------------------------
This looks great!
I need to read it more thoroughly but one thing I wanted to add was making sure
users enable GC logging, proper log rotation and heap settings for their
zookeeper installation. This can greatly help in debugging the root cause when
dealing with cluster issues.
> Ref Guide: Improve Setting Up an External ZK Ensemble page

> 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.
