[jira] [Resolved] (SOLR-13502) Investigate using something other than ZooKeeper's "4 letter words" for the admin UI status

["Erick Erickson (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-13502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Erick Erickson resolved SOLR-13502.
-----------------------------------
    Resolution: Won't Fix

I don't find anything that looks useful.

Plus, this is very low-benefit, we already have a workable solution that nobody's complained about since 8.2, so I don't think this is worth the effort.

If someone else wants to take it over, it can be reopened.

> ZooKeeper 3.5.5 requires a whitelist of allowed "4 letter words". The only place I see on a quick look at the Solr code where 4lws are used is in the admin UI "ZK Status" link.
> In order to use the admin UI "ZK Status" link, users will have to modify their zoo.cfg file with
> {code}
> 4lw.commands.whitelist=mntr,conf,ruok
> {code}
> This JIRA is to see if there are alternatives to using 4lw for the admin UI.
> This depends on SOLR-8346. If we find an alternative, we need to remove the additions to the ref guide that mention changing zoo.cfg (just scan for 4lw in all the .adoc files) and remove SolrZkServer.ZK_WHITELIST_PROPERTY and all references to it (SolrZkServer and SolrTestCaseJ4).
