Fabric8 内で事前にパッケージ化された ZooKeeper を実行しようとしています。3 つのインスタンスが作成され、アンサンブルとしてリンクされます。しかし、Pods UI からログの 1 つを開くと、次のようなエラーが表示されます。誰も修正方法を知っていますか？

Zookeeper は最初に開始し、到達可能なすべてのインスタンスへの接続を試みた後、リーダーの選出を試みます。どのインスタンスにも到達できないようです。

ファイルのエントリを更新するのを忘れた可能性がありzoo.cfgます。デフォルトのzoo.cfgは次のようになります

tickTime=2000
dataDir=/var/lib/zookeeper/
clientPort=2181
initLimit=5
syncLimit=2
server.1=zoo1:2888:3888
server.2=zoo2:2888:3888
server.3=zoo3:2888:3888

一意のホスト名に解決される適切なホスト名または IP を使用して、zoo1、zoo2、zoo3 を更新する必要があります。

  • すべてのノードでローカル DNS またはhostsファイルを更新して、すべてのノードが (IP ではなく) ホスト名で他のノードを認識するようにします。

また

  • zoo.cfgノードのホスト名の代わりに IP アドレスを使用するように、ZooKeeper の構成 ( ) を変更します。

ZooKeeper はホスト名を解決しようとしますが、解決できないため、エラーが発生します。
