こんにちは、

私のSolrクラスターをセキュアにしたいと考え、Zookeeperクラスターのchrootにsecurity.jsonを追加しました。しかし、次のログエントリが常に表示されます：

2024-11-20 07:09:14.036 INFO (main) [c: s: r: x: t:] o.a.s.c.c.ConnectionManager Client is connected to ZooKeeper

Consider configuring authentication/authorization before exposing Solr to users internal or external. See https://s.apache.org/solrsecurity for more info

Zookeeperを使用したSolrセキュリティを有効にする場合、Zookeeperへのアクセス制御をセキュアにすることは必須なのでしょうか？

よろしくお願いします。
