ローカル HBase テーブルにアクセスする Tomcat Web アプリケーションをデプロイしています。Tomcat 7.0.47 と HBase 0.94.6 (HDP 1.3.2 から、Ambari でインストール) を実行しています。webapp を実行しようとすると、catalina.out でzookeeper.znode.parent不一致エラーが発生します。

hbase-site.xml のzookeeper.znode.parent(/hbase-unsecure) の値が正しいこと、および webapp の hbase-site.xml ファイルがそれと一致することを確認しました。HBase はそれ自体で正常に動作しており、テーブルを作成してデータをロードすることができます。したがって、ミスマッチがどこで発生しているのかはわかりません。私が考えることができる他の唯一のことは、zookeeper.jar が別の Zookeeper.znode.parent の場所を定義してコンパイルされたことです。
