フェニックスを使用してHBaseを保護しています。クライアントが起動するとうまく動作します。私はHBaseにデータを問い合わせることができます。 Phoenix JDBC接続が接続プールにあり、終了しません。しかし、数時間後、私は同じ接続を使ってHBaseから何も照会することができません。私はアプリケーションを動作させるためにクライアントを再起動する必要があります。エラーメッセージは次のとおりです。フェニックス接続で、「Kerberos tgtが見つかりませんでした」というメッセージが表示される

ありがとうございます。資格情報を更新する方法はありますか？私は自分のアプリケーションを起動するときにkinitをやっていないし、Phoenixクライアント自体によって資格が初期化されていると思う。 –
Phoenixはそれを自動的に処理していないようです。あなたのアプリをコーディングするか、JIRAトラッカーに機能要求を提出する必要があります。 – kliew
