プライベート Hadoop クラスターに対して hbase プロセスを起動する必要があり、最低限の機能を示すだけで済みます。デモンストレーションでは Hadoop のインストールは不要です。シェル経由で失敗したQuickStartApache hbaseドキュメントに従うと、自己完結型のMavenプロジェクトを使用して失敗を再現できました。 /etc/hostsは問題ではありません。
これと同じ機能を実証するために構築されたように見えるMavenプロジェクトを見つけ、依存関係を更新しました。
そのプロジェクトはここにあります: hbase-demo
結果を繰り返すには、シェルと maven がインストールされた 2 行が必要です。
git clone https://github.com/jnorthrup/hbase-demo
cd hbase-demo
$ mvn clean package exec:java

このデモ コードを復活させるための助けをいただければ幸いです。hbase-site.xml をいじっても、シェルまたは maven のいずれかを使用して、スタンドアロンでの飼育係の失敗に大きな違いはありません。
ありがとう
