$ bash -c "$(curl -s https://install.prediction.io/install.sh )"で PredictionIO をインストールしました。
pio statusを実行すると、次のメッセージが表示されます。

By default, HBase manages its own ZooKeeper, so if you have not configured HBase to use an external ZooKeeper, that means your HBase is not started or configured properly.

https://docs.prediction.io/resources/faq/で提案されているように、 $ ~/PredictionIO/vendors/hbase-xyz/bin/start-hbase.shでHBase を起動しようとしましたが、同じエラーが残ります。
私が試すことができる他の解決策は何ですか? Zookeeper を手動でインストールする必要がありますか? (クイックインストールですでにインストールされていると思いました)。ありがとう!
