Alan Woodward commented on SOLR-9659:
-------------------------------------
bq. this patch adds a significant amount of new code to Solr
It's not that big, is it? The follow-up patch is a lot bigger, but that's
mainly removing code that already does what this does, only duplicated in
multiple places, and wrong in a couple of them.
If people are really against this, then I'll close the ticket. But I think
it's a significant improvement, and I don't see any other ways of doing this
incrementally.

> We have several components which need to set up watches on ZooKeeper nodes
> for various aspects of cluster management. At the moment, all of these
> components do this themselves, leading to large amounts of duplicated code,
> and complicated logic for dealing with reconnections, etc, scattered across
> the codebase. We should replace this with a simple API controlled by
> SolrZkClient, which should make the code more robust, and testing
> considerably easier.
