Subject [jira] [Commented] (SOLR-13502) Investigate using something other than ZooKeeper's "4 letter words" for the admin UI status
Date Thu, 30 May 2019 18:02:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16852145#comment-16852145

Erick Erickson commented on SOLR-13502:
---------------------------------------

Two reasons:

1> AFAIK, this is the _only_ use of the "4-letter words" in Solr, seems a bit awkward.
2> existing users who upgrade will not be able to use existing zoo.cfg files and we'll
have to deal with that set of questions.

That said, I don't have strong feelings on this. If it's easy, I think it would be a good
change. If not, not worth the hassle.

> 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).
