Eric Pugh commented on SOLR-14115:
----------------------------------

I noticed in 
[https://solr.apache.org/guide/solr/latest/deployment-guide/taking-solr-to-production.html#zookeeper-chroot]
 a reference to the "bootstrap" capablity.  I feel like that is an older 
artifact that isn't used, and we never listed it as something to port to 
bin/solr zk subcommands.    I'm not going to preserve it unless someone speaks 
up that it's actually a "good thing".  It feels very opaque to use...   and I 
suspect isn't actually used!

> I think it's a valid argument that these have outlived their usefulness and 
> we should remove them and have APIs to do what Solr requires. Especially if 
> we can find and point to a third-party visual ZK tool for _changing_ 
> arbitrary data in ZK. Zookeeper 3.5.5 has the admin server which has a UI 
> (although I don't see how to change data in ZK with it. Haven't looked very 
> much).
> While we're ripping stuff out of Solr, are these candidates? It would break 
> my heart to rip ZK support out from bin/solr, but all good things must come 
> to an end. Why do we maintain three (zkcli, bin/solr and the APIs) ways of 
> doing the same thing?
> Mark put the zkcli stuff in before we had APIs to do what Solr needs to do 
> with ZK, mainly uploading configsets at the time. I put the zk support in 
> bin/solr also before the APIs existed because I thought having to learn our 
> custom wrapper for ZK was yet another orphan bit of code laying around. All 
> before we had things like the configsets API.
> Personally, I'd prefer removing zkcli rather than bin/solr, but that's 
> because I originated the bin/solr code ;)
> This occurred when reading SOLR-14109, I'm not entirely sure what I _really_ 
> think about it.
