問題

アップグレード処理中に以下のElasticsearchExceptionがスローされ、アップグレードが失敗します。

このエラーを回避するにはどうしたらいいのでしょうか？

Environment

  • Liferay DXPのいずれかのバージョン

解決策

アップグレード処理中は、Liferayのインデックス機能が読み取り専用に切り替わるため、Elasticsearchでのインデックス操作はなく、アップグレード処理終了後に完全な再インデックス処理が必要となります。

それにもかかわらず、Elasticsearchサーバーが利用できない場合、Elasticsearchクライアントモジュールは正しく初期化できず、報告された例外を引き起こします。

この問題を回避するために、あなたは

  1. アップグレードを実行する前に、LiferayのElasticsearchクライアント構成をリモートモードからエンベデッドモードに変更してください。
  2. この記事 のように、設定ファイルを使用して行うことができます。
  3. アップグレード処理を実行する
  4. アップグレードが終了したら、ステップ1の設定変更をElasticsearch組み込みからリモートに戻す
  5. フルリインデックスを実行する
