HBase-The definitve guide から例を実行しようとしましたが、このエラーに遭遇し、それを乗り越えることができません。それが役立つ場合、私はスタンドアロンモードで実行しています。
Exception in thread "main" org.apache.hadoop.hbase.MasterNotRunningException: �

しかし、私の HMaster プロセスは実行中です。

これは私の hbase-site.xml ファイルです:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///usr/local/hbase/hbase-data/</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/usr/local/hbase/zookeeper-data/</value>
これは私の /etc/hosts ファイルです:
127.0.0.1 localhost
127.0.1.1 ubuntu
127.0.0.1 ubuntu.ubuntu-domain ubuntu
具体的には、第 3 章の例を実行しようとしていますが、セットアップが実行されない理由がわかりません..
どこが間違っているのか分かりますか？
