私はCDH 5.8.4のクラスタを持っています。私は、cloudera spark-hbaseコネクタ、すなわちHBaseContextを使用してHBaseから/にデータを読み書きするスパークストリーミングアプリケーションを起動しています。 私はアプリケーションを起動すると、プリンシパルとkinitをspark-submitスクリプトに与えます。 7日後、HBaseコンテキストに関連するチケットのKerberosの有効期限に関するエラーが発生してアプリケーションがクラッシュしました。これは、エグゼキュータのログからのエラーです。spark-hbaseコネクタが切れたチケットのケルベロス

この問題を解決する方法を知っている人はいますか？ 事前に感謝します。 Beniamino
'spark-submit'を実行するときに' --principal'と '--keytab'オプションを使用しましたか？ – MaxU
はい、私はしました。エグゼキュータキャッシュ内のチケットの有効期限が切れると、7日ごとにエラーが表示されます –
ダンプをフォーマットして「いくらか読める」ようにしてください。同様のトピックについてChris Nauroth（HortonWorks、HBaseコミッター）の答えをSOで検索してください。 –
